Yupp.
But I want to keep developer option enabled.
Cauz I use running services,simulated colour,animation scale, etc.
Anything possible without disabling it?
It is not possible to remove the developer options menu from the Settings app. You would need to modify your system to do that, which you can’t do with a locked boot loader. The best you can do is try to hide the Settings app perhaps, but for modifying the settings, it is not possible under these constraints.
