/sys/class/thermal/ not populated on Pi4

When attempting to reference /sys/class/thermal/thermal_zone0/temp to determine the temperature of my Raspberry Pi 4 on Fedora 37, that path isn’t available. I added bcm2835_thermal to autoload (bcm2711_thermal had already loaded), but that hasn’t helped.

I do see this in dmesg:

[   19.917444] thermal_sys: Failed to find 'trips' node
