Can’t get rid of remote management, even after reinstalling OS

I have an old Macbook Pro that was previously managed by Mosyle. I’ve tried to remove it by 1) Erase Content & Settings and 2) reinstalling the OS however upon the first start up after the reinstall, I’m greeted by a Remote Management configuration window. How can I fully remove this software? It’s worth noting that I cannot access anything outside of the first few initial set up screens. Thanks!
