Create a system to move between rooms and only simulate the room the player is in

I am wanting to make a game similar to The Binding of Isaac where the player will move between dungeons and each dungeon will have a series of rooms that the player can move between, but the only the room the player is currently in will be simulated. I am brainstorming ideas on how to actually do this practically but I am very new to Unity so I was looking for some guidance, should each room be its own scene? is there a way to just make one big scene with loads of rooms in it? Im not quite sure.

I already have an idea on how to make the camera move between rooms using a cinemachine I just dont quite know the best way to pin down moving between individual rooms.

Any game that has attained any popularity whatsoever has a Youtube tutorial for how to make it in Unity.

In this case,

There’s probably many others, and there are definitely many other tutorials for the individual parts that might go into a procgen dungeon game like BoI.
