Given that the great big energy efficiency gains from LED lights comes from using just two emission bandgaps, one in the red part of the spectrum and another (the most efficient) in the blue - then surrounded by a phosporous layer to smooth the emission to cover more wavelengths than just those 2 - I doubt your suggestion would be possible without pretty much throwing away most of the energy efficiency of LEDs.
It makes more sense to, for those who need such things, have separate lamps with different technologies more suitable to emit in those wavelengths (incandescent is great for IR because it’s quite literally heating a piece of wire until it is so hot it emits light so you can tune it to be mostly IR, whilst various gases used in fluorescent lamps actually emit in the UV range, hence why the “colder” color fluorescent lamps have this white powdery layer inside the glass, as that’s a substance that absorbs the UV light and re-emits it mainly in the upper part of the visible apectrum, hence why it bluer white).
In fact I think you can do so already (get both IR and UV lamps) but their form factors might not be very practical as those are specialist devices for things like heating terrariums or illuminating signs which have elementes painted with fluorescent paint.
