You CAN use a wireless PC ADB connection between the Computer and TV (make sure usb debugging is enabled and ADB link FOR WINDOWS is recommended) and connect to the android tv device using the TV’s IP adress in adb link and it should ask you to authorize it on the TV and after that click “ADB Shell” in ADB link then when it comes up use the command “pm uninstall -k —user 0 (app package name)” it will remove the app but it will still show in system apps with no data and unable to open them also by app package name i mean when you open the app and it gives options to disable it etc under the app name you should see “com.something.android” type that in the place where i put app package name and theres 2 -s before user 0 and make sure you type it exactly how i did it (minus the app package name example part you gotta add the app package name of the app ur gonna delete) and just repeat for all bloat apps idk if they come back but it does work.
What you have showing are channels. Are you saying you don't use the apps that correspond to them? Did you disable the actual apps or just turned off the channels. Those don't seem to be the kind of apps that would be system apps, but I don't know what important in your country.
Maybe you should consider using custom launcher like ATV Launcher.
try disabling them.
