Don’t worry about de-attaching the front panels and the glue strips holding them.
Obviously, you will first have to remove all screws. After that, the glue strips will hold the speaker driver panel and the PSU/AMP panel in place. The glue strips function as gaskets.
Nevertheless you can push a flat hand screw driver (actually & literally with a flat head), just underneath the panel, and push it up a bit. Do it slow, and as soon as it comes a Biot loose, move the flat head down a few centimeters, and so on.
“In the meantime do you know if not using them will slow down the process (less heat) or as this nothing to do?”
The heat inside the cabinet makes the foam deform. As Long as you do not use them, the process will of foam rot will not continue. Be aware though that the damage might already have been done. Some times, some of the copper tracks on the PSU PCB are eaten away. And sometimes that’s even hard to see with the eye. But this is easy to solve with some by-pass wires.
