The option is you have to buy another machine. There are mac ec2 instances and several mac cloud hosts that all would abuse this if they could, instead to stay compliant they buy more machines.
So I asked the IT dept and they said it's stupidly expensive to run a MacOS instance on EC2, and that they would just send me a Macbook Pro instead.
I wish I were kidding.
It is like 3 days running the EC2 buys you a Mac mini? And you can only rent the machine in day increments
And macOS remains a toy for use only by individuals that is a massive pain for developers to support.
