DOCP is just Ausus's name for XMP. BIOS is supposed to read XMP from memory and set (almost)everything by it. If you make BIOS use same settings it should be the same.
I said "almost" because BIOS may deviate some settings from XMP as developer may feel it's necessary.
XMP doesn't contain data far all possible memory settings and BIOS has to guess or adjust some settings some times by trying different settings during POST (Memory training) resulting in multiple BOOT tries. If you make those settings manually it just uses those settings no matter what with various success rates.
