Having multiple sessions on Mac with same user

Hi, I have a shared Mac system running on BigSur 11.4 - which I access from office and home. I have a single user id, and do not want the two sessions to interfere with each other. Can I have 2 independent sessions on this Mac machine for the same user ? Basically, I am seeking guidance on ‘what kind of options/settings/helper applications' will allow me to do this. Thanks in advance.
