BIOS will almost certanly be reset after update and you'll have to set up everything again.

The general advice would be 'Do NOT update BIOS if everything is working fine'. BIOS updates are usually minor targeted fixes for certain issues people encounter, or updates to support new CPU, etc.

The release notes for a24 state that the update addresses issues with Meltdown and Spectre so yeah I would say you should do it. Just go through your current bios, page by page, and take notes or pics of all the settings so you can change them back. Are you concerned you won’t see anything on screen because of the graphics card after an update? If there is integrated graphics you should at least be able to use that initially.

Dell has used UEFI BIOS since the Optiplex 780. There probaly isn't a legacy BIOS for that. Are you sure you didn't set it TO legacy compatability mode?

The guy I bought the computer from may have but it was in legacy mode when I got it was a pain to switch it.I finally watched a video made by intel i think that finally took me step by step and I was able to get it in uefi .I looked in to the spectre and meltdown that does seem scary but so is switching this bios again lol.
