The Switch is perfectly capable of both deferred shading and HDR, which are themselves independent unrelated techniques. You can make an argument about whether or not those are the best implementation trade-offs for that hardware, taking performance and desired visuals into account. But there's nothing inherently preventing you from doing it on the Switch and it's a fairly capable GPU in its own right.

P.S. Unreal Engine reintroduced forward (non-deferred) rendering as an option last year because it's more efficient in VR.

True, but deferred shading takes up extra performance, in most cases, thats why it is less used on lower end systems or vr where you need 120fps. i did not claim hdr or deferred was impossible on nintendo switch.
