If a register is read-only, QtHardMon should check if the writeable companion register (see the dependency ticket) exists. If yes, it should allow writing by redirecting writes to the writeable companion. It should somehow notify the user that this is happening, e.g. by changing the label of the Write button into "Write (DummyBackend)" or so.
This ticket depends on ChimeraTK/DeviceAccess#33
