No vehicle has that capability to do that in LEO. The impulse
requirements are large. GSO spacecraft do it at attitude where the
velocity requirements are much smaller

At what point do they adjust their orbit during launch ?

Do they fly straight east from 28.5 and "turn" once they reach the
descending node at equator ?

Or do they fly south east on launch until they reach equator and then
turn where they accelerate into proper due east ?

Or do they actually reach 28.5 LEO, and only while boosting to geosync
altitude do they adjust the orbit to become equatorial ?
