Samsung Galaxy Book4 workarounds for Linux

Running Fedora 40 on my Samsung Galaxy Book4 (NP750XGJ-KG2BR).

Workarounds

Volume below 10% is inaudible and at 100% isn't high enough (probably Dolby Atmos module fault, can be workaround by increasing the volume over 100%)
Dedicated buttons don't work (probably ACPI dedicated buttons, which can be rebinded in some useful way)
When integrated monitor brightness changes the system struggles
Intel Xe Iris does not seem to be activated, maybe unrelated but can be associated with Xe Iris's "poor implementation"?
Slow charging, needs to plug charger before boot to be able to fast charge (Fixed #1)
Sometimes boot slowly accusing ACPI Error and in boot logs
Sometimes slow wake up from sleep, takes from 1s to 20s to wake up
