@SeanTheITGuy You're not using the vendor kernel, so it's to be expected that not everything works.

@Kemal You need to activate them by enabling the correct pwm. See /boot/dtb/rockchip/overlay/
Add the one(s) you need to /boot/armbianEnv.txt at overlays=
For example:
overlay_prefix=rk3588
overlays=pwm1-m1 pwm2-m1
 
You can find the right pwm numbers in the manual

You should use "sudo armbian-install" to install from the sd-card to the nvme. It should copy the boot partition to the /boot folder, so only one partition. After installing to the NVME you should also write the bootloader to the MTD.
 
If it still doesn't work check if the M.2 storage isn't SATA, otherwise you should write the SATA bootloader. To do that you could use the Armbian instructions from:

@Joel @amazingfate Just tried the 6.1 image (Armbian_24.2.4_Orangepi5-plus_jammy_vendor_6.1.43_kde-neon-amazingfated_desktop.img.xz) and installed to the NVME (with only 1 ext4 partition) with armbian-install. Initially it didn't boot, there are no files in /boot. After copying the files from the boot partition of the SD-card to the /boot folder of the NVME and changing the UUID in armbianEnv.txt to the UUID of the NVME it boots.

Use the version compiled for the panfork drivers and run it in Wayland.
Do you have the "--use-gl=egl" flag added in /etc/chrome-browser/default?

You could install the kernel from the debs folder, output/debs/linux-image... Mr Hacker😀
When you update the kernel from the apt repository you will loose the WiFi driver again. 
To build only the kernel as in the manual: ./compile.sh BUILD_ONLY=kernel KERNEL_CONFIGURE=yes BOARD=orangepi5 BRANCH=legacy
