MKS Monster8 v2 max amp for neopixel

[TheSin-]

I can not find info for max amps on the 5v rail. I tried to run a cm4 off the pi port but kept getting under voltage so I assume it’s less than 3amps. Now I’d like to run 2m of neopixel 60 which will need 1amp per meter. There is nothing else on the 5v rail is there 2amps avail?
