Two Separate Internet Services, Same House?

Hello,

My office will be going to remote working going forward.  During COVID I have been working from home and noticed at times my internet drops.  My router is located downstairs and my office needs to be upstairs.  I have purchased extenders etc and it has gotten better (we pay for 600 mbps) but still not consistent. 

My question is can I purchase another internet service and have a dedicated router wired and placed in my office so I can wire my work computer?  The office is above the garage so I think they can get a line up here but am not sure.  I just want to work during the day (all of which are Zoom calls) and not worry about connection speeds etc.
