NVME boot for reterminal DM

hi, im trying to get the reterminal DM to boot via the nvme drive. i’ve followed the guide from It took me 2 months to boot CM4 from NVMe - NotEnoughTech and have done the eeprom update and the cloning to the nvme. however, as far as i can see, it keeps booting from the emmc. is there a better, more specialized guide for the reterminal DM? is there a specific nvme that may need to be used? any additional data i can provide to help with this?

thank you
