Can I rewrite a non-bootable eMMC from the PBP itself?

I was playing with different OS images and decided that since I was able to successfully boot from SD card it would be OK to overwrite the eMMC module image.
I dd'ed a Rock64Pro (bionic-minal arm64) onto the eMMC and now it won't boot anymore, neither from eMMC nor SD.
I was able to eventually start from SD by disabling the eMMC via the internal switch, but since I can't see it I cannot write to it.
How can enable the eMMC but bypass it at boot in order to rewrite it from the PBP itself (I don't have any other equipment to which I can attach the eMMC).
I have enabled the serial connector and do have a serial console adapter that I can connect to a Linux box, and probably attach to via minicom.
