How do I change from controller to kb/m on xcloud browser without a controller?

I do not believe there a single Title with Mouse and Keyboard support that puts M&KB against Controller. To my knowledge they all have a lobby system set up that puts you in games with controllers players or M&KB players. Some would also argue that controller
has an advantage over M&KB, to each their own.

But I'm not talking about a game supporting M/KB, but more XCloud supporting M/KB on titles that do have support for it like Halo Infinite.(Which you can blatantly see in the settings menu, having Keyboard and Mouse support in the XCloud version)

XCloud currently just forces you to use a gamepad no matter what.

😐

I don't see how it's unfair. Some people are good with controllers, some people are good with KB/M. Everyone should be able to use what's right for them. I tried to play some games on Steam with a controller and none of them would work with it. I can't use
KB/M very well because I've (like most of you) trained my thumbs for controlling videogames.

Never played Diablo 3, so I'm curious to see how a game seemingly focused on M/KB will translate to a controller.

XIM does not emulate a 360 controller wholesale. A wired controller is required for operation. XIM translates KB/M to 360 controller inputs. The 360 controller is required for encryption purposes.
