How likely will Rog Ally have secure boot support?

I play FIFA 23 on pc but wasn't able to on Windows 11 on Steam Deck because it didint have secure boot support. Rog Ally will include windows 11 so how likely will it include it? Windows 10 runs fifa 23 on steam deck but Rog Ally will have a modified version of windows 11 that Asus created specifically for it.
