Would attaching some temporary adhesive weights to the trainer flywheel during the calibration test be an effective way to cheat? My Tacx Neo 2T doesn't even have a calibration process, but maybe that could work on other models. Of course that won't affect the separate data stream sent from the power meter on the bike.

I've made some assumptions, which on reflection could be incorrect.

My Tacx Flux does a spindown test where you spin it up to a high RPM, then stop pedalling and it measures how long it takes to stop. I guess it's actually trying to get an accurate measure of the resistance being applied.

A heavier flywheel will be harder to spin up, but will also take longer to spin down at the same resistance, so maybe that doesn't make a difference.

Pressing something against the flywheel would make the trainer think it's applying more resistance than it really is, so I'm pretty sure that would work.
