Set up new HP Fury workstation laptop with Windows work/school instead of personal account

Purchased brand new HP Fury laptop with windows 11 pro. At initial setup, chose work/school instead of personal. It’s now asking me to enter an administrator username and password to download Chrome browser and/or other applications including making changes on laptop…. Is there anyway to reverse/ change back and create a personal account or is this irreversible? Only other route I’m seeing is a reboot using a USB stick.

Any help is much appreciated…. Thank you in advance.
