Temperature change when printing multiple materials(PETG/PLA/ABS...)

Machine:Prusa i3 MK3S+ with MMU2S
I want to print use different material filament in one print, like PETG print support with PLA / PLA combine TPU...
Most articles I found they use the same printing nozzle temperature for 2 different material.

I want to know if there is any method to set different printing nozzle temperature for different materials in one print?
(by printing parts not at layer height)

I found some articles use G-code M104 & M109 to control the nozzle temperature. Maybe suggest same related tutorials or articales.

Many thanks

PrusaSlicer/OrcaSlicer should do that automatically, you don't need to do anything. Just set your PETG and PLA temperatures respectively and slice, check the GCode you'll see that before tool change commands (Tx) you have "M104 Sxxx" commands setting the temperature. Tbh, I'm just trying that, and my problem is that the "first_layer_temperature[0]" is returning the PETG temperature where as my first layer is all PLA, otherwise the GCode is okay...

EDIT: I solved it by setting the first material to PLA and one of the 2, 3, 4, 5 to PETG... This is now starting with PLA temperature...
