Continuing with the theory that Grogu was never meant to be in this season (he was meant to be with Luke - you could remove him and it would have had zero impact to the plot), I doubt he will be doing much of anything.
I also wouldn't expect a huge space battle. The foundations here were laid in the battle on Concordia and then the Shadow Council meeting. Moff Gideon had a fleet which was big enough to pose a threat to the Mandolorian fleet (with the element of surprise on their side). He lost some of it on Concordia, and that portion has now been replenished. That will be the extent of the Shadow Council's help - the fleet needs to remain small enough to plausibly be the property of a petty warlord.
Axe Woves will successfully warn the Mando fleet. And as a result, that Star Destroyer will wipe the floor with Gideon's fleet (there will be a bit more to the scene to build tension, but this will be the reality). And on the ground, Bo Katan is going to wind up saving the day, mounted atop the Mythosaur.
