Okay? But I’ve never been in an office or seen one where they banned bringing in your own equipment. Even in places that had the set menu for different roles. If you had some stuff you wanted to bring in, go for it.
So yeah, these sorts of workplaces exist and thousands of people have to contend with their on-site limitations.
If managed to bring through securty some stuff that you plug into the office network, isn't certified and something goes wrong, short circuit or whatever, it is on you to deal with whatever might happen including dealing with the insurance company.
