A stupid solution would be try 200 or so times and then assume no card there

The log in pftf/RPi4#77 seems interesting. Notably that consistent "ERRI MmcStatus 0x18040" being an indicator of card absent. The alternative which comes to mind is adding something to the command-line to tell it to skip trying MMC.

I kind of maybe unrelated question, but from what I had gathered the in-CPU bootloader only looks for stuff to boot on the sdcard, so how can you get this UEFI bios running, without an sdcard?

That is not the case. The Pi 3 and Pi 4 on-die bootloader code is able to perform a lookup for boot files that reside on a USB drive. If you use a recent EEPROM with a recent start4.elf, you will get straight to USB boot.
