Making sure Mac M1 doesn't have tracking or screen-capturing software
If your employer installs management software, you should not use it as a personal machine, or do so with the expectation it's being tracked. The computer is your employer's property so if they tell you to run a certain enrollment process you should not try to work around this.
If it's appropriate to use this as your personal computer, you can and should follow the steps to wipe your computer: https://support.apple.com/en-us/HT212030. This will ensure you know all the software installed.
