Hello there! I am Charity. I'm glad to help you today!
Thank you for the information. May I ask if you are using a company-owned computer? If so, I would suggest contacting your IT department that is managing your computer. They control the settings via group policies or MDM tools, and only they can lift the restrictions in that case.
Kind Regards,
Charity
Please note that things might need more than one reply to completely resolve your issue, as it will completely depend on the complexity of the question and the amount of detail that you have provided me.
