How to change OAuth2 Refresh Token Lifetime on Cloud (sugarondemand) instance?

Hi everyone, I hope the end of the year is treating everyone well!

We ran into an issue with a client using our integration and their refresh token lifetime was only set to 1 hour. We need to have that increased. 

What is the process for doing that on a cloud instance? According to the docs it looks like it's a configurable item. 
Also, I noticed in the docs it mentions this does not apply to SugarIdentity (IDM) instances. Is there somewhere else to configure that? Or is it managed differently? From what we can tell even on an IDM instance the refresh tokens lifetime respects the config value.
Any help here is greatly appreciated. Thanks!
