Set MAX_NUM_NODES super low in your variant.h, and see if it gives you enough headroom. I merged locally and attempted this. Getting errors

The RNG stuff is from a double macro definition in the used crypto lib. i might swap that out for another one. locally it builds with a modified copy. Maxnodes is a good pointer...
Another flash saving potential is the unishox library. It's only actually used for ATAK packets. #ifdef it out of existence, to save a few more bytes.
Another idea for saving flash is to remove all the I2C stuff. It wouldn't be needed for a minimal build but is still included as far as I can tell.
