Microsoft/Xbox will not release Avowed as a physical disk. All physical releases only include a download code.
IGN published the list of all versions of Avowed: https://www.ign.com/articles/where-to-buy-avowed-xbox-pc-premium-edition?utm_source=instagram
There is only a "premium" physical edition, but it only includes a code in a box.
The standard edition is only digital.
