What about a DIP or SOIC test clip?

We use those little spring loaded test terminals into a pth hole the
ones with a spear point and a scrap pcb underneath them they go in on a
0.1 pitch. Ew also disconnect the VCC and the data lines with little
jumpers until the program is finished (the programmer cant handle the
currents of the whole circuit often so it only powers the device

I've done this, programming ISD chips using edge connections, plugged into a
card-edge connector. Just picked up sufficient of the connections for my needs,
left the others blank. PCB had to be carefully positioned, I aligned with one
end, to avoid cross connections.

It needed care but worked fine. Programmed many dozens this way, it's what I'd
do for a few hundred off.

Why not have the chips pre-programmed before soldering to the board?  What I
have done currently is to add a header, unstuffed, so if I need to mod them
once released I can but for production they will be pre-programmed
