Are you able to add station-only reactor blocks to the config? If so, a potential way to lock out shield regens from being used on ships is to up their power costs by a few orders of magnitude, and create reactors (which only stations can use) with similarly buffed output. To ensure that other things still balance out nicely, you might also increase the power costs of other station-only blocks, I guess.
There wouldn't be any need for these reactors to be expensive, as long as only stations can use them, and the cost for shield regeneration is too excessive for ships to utilize. Perhaps the recipe could simply be 1:1 with normal reactors, with the opposite recipe for converting them back.
