Payload capacities to trans-lunar injection (source wikipedia):

SLS Block 1: >27,000 kg (59,500 lb)

SLS Block 1B: 42,000 kg (92,500 lb)

SlS Block 2: >46,000 kg (101,400 lb)

Vulcan Centaur: 12,100 kg (26,700 lb)

New Glenn: 7,000 kg (15,000 lb)

Orion crew module by itself weighs 10,400 kg (22,900 lb), the service module is 15,461 kg (34,085 lb).

Orion is a heavy spacecraft. SLS, like or not (I don't), it has a lot of lift. Unless you're sticking an Orion inside of a Starship (lol), Orion basically dies with SLS.
