How to remove Xbox Dev Mode get back in Insider Ring?

No not the insider Programm i think I use the officail dev mode app to switch my xbox to dev mode from retail

Updating to the latest version of the Windows Insider Dev (formerly the Fast Ring) build fixes this problem.

Are you an Xbox insider by any chance? If so, then constant updates are normal, especially when the update is getting closer to public release. If you are getting sick of them, you can either change release ring or leave the insider altogether, just download
and launch the Xbox insider hub, and from there you can change rings or remove the console from the program altogether.

For more info on the Xbox insider prgram have a look at the insider forums here https://www.reddit.com/r/xboxinsiders/ or on the insider page on xbox wire https://news.xbox.com/en-us/insider/

Also if you're not in an Insider ring and it's the games getting updates the only way to alleviate this would be to leave it in Instant On mode like Smwutches said.

Accessing the higher ring levels in the Insider program requires you actively participate in the provided Insider Hub "quests", submit regular feedback and bug reports, fill out surveys and polls, and use your console
often.

In this program, the most dedicated users to the Insider Hub will be able to access the Alpha and Beta rings, which get them the privilege of bug-testing the cutting-edge feature implementations first.
