UPDATE You can download Orcs Slicer Anycubic beta at: MacOS: https://workbentch.s3.us-east-2.amazonaws.com/acslicer/prod/anycubic_slicer_beta_based_on_orca_v0.1.0.dmg
Orca Slicer Profile for the new Anycubic Kobra 3 Combo. Use the Power of Orca Slicer for your models.
Includes: Printer Profile PLA Profile Print Profile
You can open the 3MF file and save the printer and print profile
Open the 3MF project, which should load the project with the 2 objects (they dont really matter) and in the printer tab it should say Anycubic Kobra 3 Combo, at this point you want to hit the edit button (pen and paper icon) which the printer setting page pops up, what you want to do is hit the save icon and rename to whatever you like. Make sure you select "User Preset" on the bottom to save it to your system
You can do the same with the print profile that loads in the 3mf
