Best way to split elevation data using lat/lon grids and preserve data extent

I have elevation data that I am trying to split up using a 1 degree lat/lon grid. My initial idea was I could just set the export bounds to the lat/lon boundaries using the below line as part of my export. The parameters are variables set in another part of the code.


This works but when I load in the exported file the extent of the data is the entire Lat/Lon grid tile instead of just where the actual elevation data exists. This results in a larger file size and slower draw times when the data never fills up an entire 1 degree lat/lon grid tile. Is there a good way to make the export still split by the lat/lon coordinates I give it but have the extent be fitted to the actual data in that tile instead of set to the entire tile extent?
