And if ever, it may be via third-party plugin since I can't find any Specter hardware wallet support in Electrum's included plugins.
Plugins: https://github.com/spesmilo/electrum/tree/master/electrum/plugins (all famous HW wallets are there)

I can't find KeyStone among the plugins either, but KeyStone Bitcoin Only Firmware is compatible with Electrum.

I found the documentation of their DIY wallet (the link in DaveF's reply is for their desktop wallet)
Link to Specter Shield DIY doc: https://docs.specter.solutions/diy/

And based from the "communication" options (link), it cannot support transaction export via QR since Electrum shows base43-encoded data instead of base64 in its QR code.
On the other hand, SD card should be supported since Electrum exports in PSBT format; however, signed transactions should be in hex for "broadcast" button to be available.
There's only one way to find out: try to 'export->sign->import' a transaction but don't broadcast if you don't want t send it.
