I've done some research. Am I correct in the assumption that I would need a CH341a programmer in order to dump the bios and flash it again?

Yes, you are right.
This post can be useful too.

Ok, how do I do such a thing?

I'll be honest, I'm nowhere near as smart as you guys. Could you please direct me to something I can read that will tell me how to dump my bios file

Hello geniuses, I have a Dell Latitude 5520 with an admin lock on the bios that I want to remove.

Service Tag: H62CNL3

In the bios the Admin Unlock says H62CNL3-8FC8

Please help me unlock this and possibly remove the password. Thank you

Working no display

@lapfix's BIOS from Post #261 should works fine. See if there any missing component around the BIOS chip, do verification after programming the chip and re-solder the chip again.
