Yes, the linuxcnc-uspace-dev in the bookworm repositories works with ethercat if you follow my sticky in the ethercat sction.
Support for individual ethernet cards is a matter for the developers of iGh etherlabmaster. I have not had any issues with the cards I have used including on  ARM CPU's such as Pi4B and Odroid N2+

I had linuc cnc running on deb 11.6 but latency was awful. Could you link more info on the isolcpus? Think that would fix my latency?

Im about to five up and just run it on a pi

sudo apt install grub-customizer
sudo grub-customizer
second tab it will have a field that says quiet.
change that to:
2 core PC: quiet isolcpus=1
4 core PC: quiet isolcpus=2,3
Save, exit, reboot

Note if you have an older 2 core machine its well and truly past its useby so you may need to upgrade.
