Currently, I am using Windows Server 2016 and SQL Server Enterprise 2019, but the SQL system only utilizes 20 cores, even though I have allocated 60 cores to the server.
I have tried the following commands:
EXEC sp_configure 'affinity mask', 0;
EXEC sp_configure 'affinity64 mask', 0;
RECONFIGURE;
I have also checked whether the operating system detects the cores and reviewed the NUMA configuration, which shows that NUMA nodes from 3 onward are offline.
How can I bring the offline NUMA nodes online?

SQL Server detected 1 sockets with 12 cores per socket and 24 logical processors per socket, 24 total logical processors; using 24 logical processors based on SQL Server licensing. This is an informational message; no user action is required.
(This is from my desktop at home, running Developer Edition.)
