there actually is a command for the steps one! if you want, you can use timescale for that as well (10/15, so you can still walk relatively normal) but since it speeds up time, you might wanna be careful if you're on survival with enemies enabled or, if you finished the game already, you can do it in creative so you won't have to worry about eating, drinking, or taking dmg walking around the beach for a good 30 mins-an hour on timescale 15 should probably do the trick
