My Golf 7 key was stolen.

I have reprogrammed my keys to disable the stolen one.

The thief could still reprogram the stolen key as he can open the door using the hidden emergency door lock.

Which fuse can I remove to disable car key reprogramming and/or engine start so the thief can’t take over the car?

I am aware some thiefs might know which fuse is missing, but this is as far as I am going to go for now in tampering with the car.

I don’t own OBD gear so I can’t test if “F18 5A Battery control module, data bus onboard diagnostic interface” is the right one. Also I don’t know the long term consequences of removing any of the fuses.

There is no fuse to remove that will disable immobilizer programming. You can how ever remove the fuse for the obd2 power. That will slow someone down since their tool would no longer be powered and they probably will not be prepared with the additional attachments to deal with that. You could also just install a dummy obd2 port and hide the real one behind the paneling.

Also, unless you know the cars immobilizer pin code VW's of this year are very difficult to program. Without knowing the PIN, immobilizer data and the key no longer being programmed, The thief would need to do a ALL KEYS LOST procedure to reprogram it. Its the same thing that would need to be done if it was a never programmed before key. Typically these can not be done through OBD2 alone and requires removal and disassembly of the instrument cluster.
