godtooro ,Are you using incremental refresh on your table ?
If not then it is not possible , Power BI is a "read only" system so it doesn't have the ability to store data beyond a refresh.
You will either have to modify the source system (you said not an option), or put in an intermediate process in place to store a previous day snapshot of data, then have Power BI read in the source data and the snapshot, then do the comparison.
Thanks,
