Generally, while Dell does not recommend downgrading the system BIOS due to the enhancements and fixes provided in BIOS updates.

A corrupt BIOS is one of the possible causes of your personal computer being unable to complete POST or sometimes even boot into the operating system.
If your Dell PC supports BIOS recovery, you can recover the corrupt BIOS by using the BIOS recovery method on your Dell personal computer or tablet. See the Dell knowledge-base article BIOS Recovery options on a Dell PC or Tablet for more information.
