Based on the doc linked in post #4 I think zeroing 32k starting at an 8k offset should remove enough of the u-boot from the SD for the pinephone to boot from eMMC, but I haven't tried it. Something like this, assuming I've remembered which device is uSD and which eMMC - do check!
dd if=/dev/zero of=/dev/mmcblk0 bs=1024 seek=8 count=32
