I use a GoPro suction mount (a real one ,not a copy as I think these ,at least, are better) but with a cable tether.

It is a bit like an inner 'Bowden cable' so quite thin but provides a 'belt and braces' approach.I have it located on the sun visor mount.

I wonder if Circuits would consider this acceptable...?
