Well I created 2 partitions on 32GB Thumb drive and created install media for Catalina and Big Sur then put my OC EFI folder on the EFI partition. I restarted, cleared NVRAM and did F12 to select it to boot from. I know the EFI is working because I used OC 0.6.9 and not 070beta which is on my main boot drive. Unfortunately, in the boot menu the installers do not show up.

You mean the BIOS boot menu doesn't see your USB flash drive as a boot option?
