In the old arcmap 10.8, it is simple by using the link function with the HyperLink script in the layer setting.
However, in Arcgis Pro, the HyperLink script function disappeared, the hyperlink only open the tiff in a phtot browser.
In the pop up window, only Arcade script can be used, but I cannot find a function to add raster to map by Arcade.
You would use arcpy to manipulate the contents of a map, search help for code examples on addDataFromPath().
