Is there anyway to disable/hide the brightness slider in the notification tray?

oxwivi

This is my first time using Graphene and (for context) my experience with third-party Android ROMs is limited to a few devices with LineageOS. I had thought that Lineage is pretty close to AOSP in terms of UI/UX, but it seems they carry more customization options like hiding the aforementioned brightness slider and things like the VPN status icon (the VPN icon might be more relevant to Graphene, if it's usage needs to be accounted for by the user's threat model).

I was hoping I could do similar modification to the UI using any relevant ADB commands. I've found the command, adb shell settings put system notification_panel_brightness_adjustment 0 in an old 2016 XDA Forums post, but it was already outdated by then and no longer works on the post's contemporary or current versions of Android.

Is there any known ways to do this? Or is there any comprehensive documentation of ADB commands I can reference at all?

I'm not sure about the brightness slider, but you can hide icons from the status bar using the blacklist feature in adb. You can view your current blacklist here (if it exists):

adb shell settings get secure icon_blacklist

Then make sure vpn is in the blacklist. If you want to hide multiple icons, they must be in a list with no spaces. Here is an example I used for an Android tablet but it will be similar for Graphene.

adb shell settings put secure icon_blacklist frontlight,media_mute,refresh_mode,rotate,volume,vpn

If you don't know the name of the icon you want to hide, you can find it in here:

adb shell dumpsys activity service SystemUIService | grep -A 39 "StatusBarIconList state:"

I don't know of any comprehensive guide. I found these commands by using ChatGPT, but I can confirm it works to hide the VPN icon on GrapheneOS (A15, Pixel 8). Also it's recommended to keep developer mode disabled after doing this for security reasons.
