This is a suggestion to be able to change the number of decimal places for the Coordinate Format DDM (Degrees Decimal Minutes). By default, the decimal it is set to 3 (DDD° MM.mmm') and there is no simple way to change this.
The current solution in ArcGIS Pro does not work for Data Type TEXT, only Numeric. The problem is, in order to use Calculate Geometry for DDM the Data Type has to be TEXT.
A workaround-type-of-solution was posted here, but I would like to propose a similar solution as for ArcMap Setting the number of decimal places displayed for measurements—ArcMap | Documentation where you can simply choose number of decimals regardless of Data Type or Coordinate Format.
