Just a quick question. Do you have a monitor (like the Pi 7 in touch screen) attached that is running off the same power supply as the Pi? I had a setup like that which used a splitter to power both the monitor and Pi from one power pack. My setup kept complaining of undervolting until I removed the splitter and plugged the monitor and pi each into their own power supply.
