Does the Dell installed driver 'Intel RST' require RAID mode 'On'?

Question

The flipside of my title question is:
If I have changed my system (Precision 3541) from 'RAID On' mode to 'AHCI mode', should I install the Intel RST driver after re-installing Windows 10 to my HDD?

I had to reinstall Windows after my original SSD failed. I am currently running without a PCIe NVMe installed. I installed Windows to the 2.5 in. HDD instead. Now, Dell Support Assist -or whatever it's called - wants me to install the Intel RST driver. Why is it recommending this?

If the current driver is Microsoft AHCI, the suggestion to use Intel RST will change it to use AHCI driver from Intel chipset.  It's up to you to decide.  If you choose to update and having issue with Intel driver, you can always select driver rollback option.
