There is no way to switch profiles with tlp. It has two. On AC and on Battery. You could probably script it to change profiles and tie it to a shortcut key combo. The ony other way to take care of the autosuspend issue is to use UDEV rules to do so. Tlp is probably the easiest way to take care of the dock issues that may not be BIOS specific. Also there is TLPUI floating around.
As to updating your BIOS…I would never recommend that someone update to a beta BIOS, but since Framework has yet to release a stable BIOS and that is what actually fixes all of the Thunderbolt oddities, all I can say is do your due diligence, check out the thread 12th Gen Intel Core BIOS 3.08 Beta Release and come to your own determination. I have had great success with both the update process and with running the device on said BIOS.
