According to the schematic it seems like pwm is used for that. That would need to be enabled as device tree overlay.

Not sure if there is further/DIY programming necessary to make it work.
This was fixed quite recently:https://github.com/armbian/build/pull/9039
Upgrading uboot package does not automatically rewrite the binaries. It just provides them for manual rewrite. So upgrading this package should not do any harm without actually writing the boot loader.
You're in luck. Major work has been done. https://github.com/armbian/build/pull/9049 Still needs testing
Once this is merged 4A and other more recent Allwinner Soc related work can be rebased on top of that.
That would be my best guess too.
Check other PRs which add support for boards to get some clues how to achieve. If there are questions, feel free to state.
Never heard of that spelling "ip_tables". Anyway should be built in: https://github.com/armbian/build/blob/4e027a40d6d38d5e9072577a7e47b110914a843d/config/kernel/linux-qcs6490-edge.config#L421
If that doesn't do it, try the main integration branch which for once combines all branches and for the other is actually meant to be used by megi iirc:https://codeberg.org/megi/linux/commits/branch/orange-pi-6.18
First step is to cleanup and bump the sunxi patchset to 6.18. This is a major blocker. Once that is done. Patches for more recent Allwinner SoCs can be added.
I started doing that but it is extremely exhausting. I have no clue how the-going managed to maintain that for that long... must be sort of masochistic or something lol.

I never mentioned any solution. Moving your post to an appropriate location is a forum moderation task and the post was FYI only.
I don't have this board nor do I know how to fix it.
IIRC stuff for rock2a/f was sent to upstream uboot too. Try adding a condition to use mainline uboot as well. You can check various rockchip based boards which also have this in their board config file.
This is part of https://github.com/armbian/build/pull/8777/files
And there are no changes at our end. So I assume the issue was introduced in mainline?
