My Dell Latitude e5570 appears to have a virus in my EUFI.
What I have tried:
So it is the EUFI I think.

Have you tried performing scan before Windows boot up like using Microsoft Defender Offline?
How do you know there is a virus in your system?
What are behaviors?
I didn’t want to add all this info as it is long.
I used a program from source forge to fix my grub instalation.
First I was locked out of windows which overcame by using rescatux to remove windows password . I then ran my avast anti virus which found nothing. I booted in Debian 12 and ran the av for that got nothing. Went back to windows couldn’t get wifi access. These access issues went on till I cracked and used the clean command to clean out my ssd. Tried to install windows install wouldn’t run . Can’t remember the error phrase. Tried to install Debian got to wifi setup wouldn’t access my wifi during install. Got Kaspersky boot iso and ran a scan. Found nothing. At this point I thought it was in my bios. Reset to factory defaults, however there were still settings in the bios recovery config which I thought should not be there. Started researching this and found it could be EUFI infection. This activity began in 2020 and has various types. Some suggestions include covering lead tying to a brick and tossing in the harbour. If I can’t fix this which I probably can’t I will replace the motherboard.
If you have an alternative or any action I could take I would be thankful.
Craig.

If the SSD is detected by DELL Diagnostic tool but not by your system that doesn't mean the system is affected by virus.
If your computer has multiple SATA slots, try connecting the SSD to a different slot. This can help determine if the issue is with a specific slot.
You may try checking SSD on a different machine,
