I did not modify it:

# cat /boot/efi/config.txt
[all]
arm_64bit=1
dtparam=audio=on,i2c_arm=on,spi=on
dtoverlay=mmc
dtoverlay=disable-bt
device_tree_address=0x4000
kernel=u-boot.bin

[pi4]
hdmi_safe=1
armstub=armstub8-gic.bin

So commenting out the dtoverlay=mmc line and switching
to the Rev 1.1 RPi4B to attempt a boot still results in:
