Hi Keyzer-Soze
I am an Independent advisor and fellow Microsoft user. Can you please elaborate from where are you trying to remove this filter?
If this is about the parental controls, these steps may help:
Go to Settings > Accounts > Family & other users.
Click on the Manage family settings online or remove an account option.
Select the child account for which you want to turn off parental control and make the necessary changes.
*Do note this can only be done by an adult account in microsoft family.
