I recently bought a used MBP Mid-2015 from a local shop with Mojave already installed. I wanted a clean system so I booted to recovery and erased the internal drive and started a reinstall of the os. I got an error triangle/exclam symbol and a code telling me it could not find and OS to recover from. After some googling I reset both the NVRM and PRAM. This time I was able to do a network recovery and finally got El Capitain installed. I upgraded to Mojave then Catalina, loaded a bunch of testing/diagnostics tools and checked out the laptop. The last test was to do another recovery and reset everything to factory. This is where it gets weird.
TLDR: After erasing the internal drive and doing a os reinstall from the recovery screen I got this after the post install reboot.

First, what is this, some kind of remote management left over from previous enterprise owner PWC?
Second, after wiping the internal disk and reinstalling os and resetting NVRAM and PRAM, how is this still here?
And third, how to I get passed this, I can't move forward.
