There was a port of Pilgrimage on the Sahrani map carried out by Vafana, many years ago, but probably not on Steam. The pbo is at https://www.dropbox.com/scl/fi/52n8g4xqt8lhy8nwpl5ef/Pilgrimage_1_95.Sara_dbe1.pbo?rlkey=1xwtuk70fm4dc2al40kbzbx0r&dl=0
Just pop it into the missions folder in the main Arma 3 folder, and it should appear in singleplayer scenarios when you start Arma 3.

Have you considered doing a Sahrani map Pilgrimage?
