Anyway to disable aggregation?

I recently purchased a suncomm cp520 pro with the x65 chip. I was hoping n41+n41 would give me a boost compared to x62(spitz ax) but it does not. It actually gives me significantly worse performance. 600Mbps vs 150Mbps download and 145Mbps vs 5Mbps upload. Wanted this outdoor unit so i could mount outside and not have an antenna sitting in my window. So is there anyway to disable it from getting a scc band?

This unit is also pretty hot to the touch, not sure if that is normal since the metal case is supposed to act like a heatsink. My eero did do 1 speed test of 891Mbps but never since and i’ve tried auto apn, manual, nsa and sa. Not sure what setup got that 1 speedtest.

Thanks
