I Need more help before I am game to start this Clean Install please

20H2 (OS Build - 19042.746

Good afternoon, me still "trying to do a clean install,
This Clean Install has me "hiding under the bed” Just when I think I’m right to Launch" something else allways crops up!

If I'ts may? I'll list the other Questions here? I have been at this for a month and the PC has is nearly "expired"

There are 2 Windows 10 Upgrade's that I have put on hold (for another 2 days)
KB5000802 30-Mar-2021 Security Update for Windows 10 (KB5000802)
KB5000858 27-Mar-2021 Security Update for Windows 10 (KB5000858)

What do I do about these Drivers packages DELL keep Emailing me to download?...... I don’t know if I should download and back them up to my Ex HDD until after I run my Bootable USB, If I install them before then do the Clean Install they will be deleted’ should I see what drivers the Windows Clean Install brings first

I have all the current old Drivers listed and Backed-up on the Ex HDD [F;] F, G, H, I

I'm using the OSK' which does not become active in time to push (F12) before the DELL screen during the Clean Install boot-up ? My keyboard quit stopped weeks ago and I have tokeep re-starting Windows explorer in Task Manager because 8 or 9 Mozilla FF tabs build up without refreshing and screen goes to blankand I have no Desktop icon's or anything

I don’t know if I even if I have to close Secure Boot before doing the Clean Install first see Belarc Log Re Boot Mode: "UEFI with successful Secure Boot, (in Word doc Attachment) If I do have to venture there is there a tutorial describing how to ? thanks again Kind regards Dasha

Replying to NavyLCDR,
As I surmised it's a Computer issue "not the keyboard s, if I Tap on a Key' whatever is on the screen a either a Word doc or Browser, light's up and appear's as "Dark Mode" for a second

If I Tap and hold the key' down for a few seconds the same happens. But it will type that key?
so being unable to get into "Device manager or Disc Manager, even from, File - Run New Task it comes up
"Windows cannot find Device or Disc, make sure you typed the name correctly

So if it's a Driver I can only hope that when I Boot-up during the USB Clean Install that those Driver's will have been installed as part of the process if that fail's I will be "resourcing a very Large paddle' Thank's for your help
