Hello @MRoni121, and welcome to the community.
Thanks for your post. Unfortunately, there is no way today to increase the number of records in the smart view past 500 (which should be the same limit as the table view).
Our advice in your case is to implement multiple segments, according to some filtering criteria (maybe a given geographical area), and use those sub-views to display a more limited number of markers on the map.
I hope this helps,
