My last employer had several thousand employees. Some of the IT guys knew Linux, but it wasn’t anywhere in the organization. I managed to convince them to let me install Linux on my desktop. They said sure, with the provision that I was not allowed to have a single issue. If I had an issue, they’d format it back. It was a fantastic last 8-9 years at work, as far as computer use went.
My usual reply to said employees is “if you know how to install and configure a Linux distro, you probably also know how to solve your own problems”. Everything else is pretty much deployed over AD, so if you can get to the point where you need admin creds to hook to the DCs, then do whatever you like.
Eventually, all of them failed to even get close to being a part of the AD DC and that is where the story ended.
