Description
As originally referenced in https://github.com/spesmilo/electrum/issues/5789#issuecomment-558050237, the Coldcard (and potentially Trezor in future?) supports hardware signing by PSBT file in an airgapped scenario.
Currently Electrum always asks for the hardware wallet to be plugged in when it is configured as a keystore. It would be good to support a "never ask again/use as airgapped" configurable setting on the keystore that recognises the airgapped use case.

Research direction
Start by tracing Electrum's existing hardware-keystore flow to find where it requests the device, then compare it with the PSBT file-based airgapped flow described in issue #5789. The work is done when a configurable permanently-airgapped setting prevents unnecessary device prompts while retaining hardware signing through PSBT files.
