If you are unsuccessful, Dell has options to replace the motherboard.
Dell Policy, BIOS breaks motherboard CMOS
In warranty customers If a Dell Support representative directs you to update the BIOS, and it broke the motherboard CMOS, Dell will replace the motherboard. Stipulations = * The service itself could be either onsite service or Return to Dell Depot, depending on which warranty you purchased If you updated the BIOS without any direction from a Dell Support representative, and it broke the motherboard CMOS, Dell will do a one time only motherboard replacement. Stipulations = * The service itself could be either onsite service or Return to Dell Depot, depending on which warranty you purchased * We will then ask you to not install any BIOS update unless you contact us first and have us guide you Out of warranty customers If a Dell Support representative directs you to update the BIOS, and it broke the motherboard CMOS, you are eligible for a one time only out of warranty motherboard replacement. Stipulations = * This is a one time only offering * This is a parts only service. Dell will not send on onsite technician * Dell will only have motherboards available for 5 years from the original system RTS (Ready To Ship) date. If you are past this 5 year period, you will need to purchase the motherboard from a 3rd party seller If you updated the BIOS without any direction from Dell Support representative, and the BIOS update broke the motherboard CMOS, you have to buy the replacement motherboard either from Dell or a 3rd party seller.
Before trying to recover from a corrupted BIOS, I recommend trying clearing the CMOS settings. You may wish to record your setting first before clearing the CMOS. The procedure is on page 104 of the service manual. You may also try turning off Windows 10 fast startup if that is enabled. I would not assume the BIOS is corrupted since the computer does seem to boot up normally after restart.
Thanks, I will try clearing the CMOS before assuming the BIOS has been corrupted. Speaking of that, what are the odds that three straight BIOS updates would all corrupt the BIOS in this specific way? As mentioned in my initial post, I began to experience the booting problems when I replaced 1.1.6 with the first release of 1.1.7, then the second version of 1.1.7 and finally the current 1.1.8.
There is one other (presumably) related problem I have also experienced recently. It involves the "other end" of the start up/shutdown process. I am using Windows 10 (1903). Many times when I select the "Shut Down" option under Settings, the computer appears to briefly shut down, then loops back to the Windows sign-in screen. In other words, rather than shutting down, it starts up again. When this happens, the only way I can power the computer down is to hold down the power button until the machine turns off (not a good practice, I know, but there is no other way to achieve shut down).
Thanks very much for your suggestions. Turning off Fast Start in Windows 10 completely solved both problems (start-up and shutdown). Also, I did run the Windows System File Checker, and everything came back clean (no "integrity violations").

Since your computer seems to work fine except during some startup or shutdown conditions I don't think it has an issue with a corrupted BIOS. More likely I think you have a corrupted Windows OS issue. In addition to turning off fast start, I would run the System File Checker tool https://support.microsoft.com/en-us/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system
Also I would try returning Windows 10 power plan setting to default https://www.top-password.com/blog/restore-power-plan-settings-to-default-in-windows-10/
