Static IP for SMB

I have a MBA M1 which hosts some work related documents that I need to edit via my iPad (at work and at home). I've enabled file-sharing via network and can see those documents on my iPad using a SMB connection. However, every time I move locations between home and work - the IP address for SMB connection changes and I need to go into my iPad settings to plug in the new IP. This is a huge PITA. Is it possible to setup a static IP address for SMB for my MBA so that I don't need to manually input the new IP address every single time? Alternate solutions are also welcome as long as they don't require me to use cloud services. Thank you!
