Many of the light switches in my older home are fed power first through the light fixture. The switch boxes have incoming 2-wire setup, i.e. hot (black), load/neutral (white taped black) w/ ground, so not a 3-wire setup, i.e. +traveler (red). Basically this setup:  https://i.sstatic.net/n71A1.png

I am looking at the Square D Rocker and Slider dimmers, though they appear to be made for more modern homes given the instruction guide. Any insight into whether these dimmers support a power-through-light, 2-wire setup? Both installation indicate a power-through-switch first, and a 3-wire setup.
