Hello @Avenkataanusha,
Yes, you can set up incremental refresh for multiple data sources. I’m providing a link below of an article from RADACAD. And also providing some of the links of the videos on Incremental Refresh.
Please Note: The article is was published in June, 2019 so at that time this option was available only to Premium Users but now it’s available to Pro Users as well. Apart from this, everything absolutely remains the same. So you can go through this article and set up incremental refresh for multiple data sources.
Hoping you find this useful. 
Thanks and Warm Regards,
Harsh
