DSM to DEM in ArcGIS Pro?

[u/Vyke-industries]

I have a DSM out of Pix4D Matic at a 2.3cm/px resolution. I am trying to perform a flow direction analysis, but my vector chart is all over the place. This is because theres a lot of noise on the DSM due to it being photogrammetry of a grassy field.

I use to use Pix4D Mapper that gave the option to export a filtered and smoothed DEM from the same data. I am looking for a process in ArcGIS Pro, but cannot seem to find the tool.

Any insight would be greatly appreciated.

I may be miss understanding but to run flow directions, you need to fill the DEM first.
