Abaqus - dual cpu Amd Epyc 128 core (64+64 core)

I hope you can give me some guidance on this problem. we have a machine based two epyc 7763 cpu and 256gb ram (16x16GB) , Win 10 Pro 64Bit. the machine is fine and very performing, we only have one problem with this software Abaqus Dassault system 2022.substantially during the calculation it uses only 64 cores at 100%, therefore only one cpu, the second cpu is substantially not used in fact the usage values vary between 4%, 7%. I tried to disable SMT Control from bios, but the problem persists.clearly in the software I set 128 cores, I have 38 tokens available
Do you happen to have any info on this? Thank you.
