Hello Nikhil,
AFAIK, the time for Auto Saving the content added in the cloud files depends on the content we entered into the file and the type of the content like whether it needs to calculates, insert some pictures, paste the large data, action taken on multiple cells at one time. However, there is no option to make saving to the cloud to improve performance except using a good internet connection and keeping our Office apps up to date because the syncing of content from Office apps to the cloud is not operated by any different app where it's inbuilt in Office apps.
To check whether your Office apps are up to date, open any of your Office app> Account> Update Options> Update Now.
Appreciate your understanding and stay safe!!
Best Regards,
Chitrahaas
