HP Elitebook Folio 9470m Mojave issues

Hello,

i installed yesterday "macOS Mojave 10.14.6" on my HP Elitebook Folio 9470m via Clover - so far so good.

Following functions are not working:
- WiFi + BT --> Already ordered a new card (BCM94352HMB)
- Battery percentage
- Brightness control
- Audio

Does anyone has the correct .kext or maybe a whole "EFI" pack for me?

Furthermore is it possible to run "macOS Catalina" on the HP Elitebook Folio 9470m?

Would be nice if someone could help me. :)
