kolarivision are almost certainly capable, as they offer specifically UV and IR conversion services which usually require fully disassembling the camera to remove the factory filters and install a new one. Rebuilding DSLRs and mirrorless cameras is literally their business bread and butter.

They mention they've disassembled similar cameras in the past and are aware of the costs, so either they know how to put it back or (unlikely) they don't care about it. But it's not something unexpected for them.

They made photos of how they took it apart ;)
