App lock at Huawei?

Have a question and that, at Huawei, if you already have an app locked, can you set it up so that you can't delete the apps with app lock? So that you first have to enter the code to delete the apps with an app lock? Is that possible? Because my brother keeps deleting the apps because he can't get it and shouldn't either.

How about completely locking the cell phone 🤷🏼♂️

Yes, the problem is that my father owns the cell phone and I'm sharing it with him right now because I got my weight off😅
