The parameter named "Maximum Batch Threads" on the "SysServerConfig" auto defaults to 16 ever night even if you change it. This is due to batch auto scaling (https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/sysadmin/batch-capacity#batch-auto-scaling). Considering it can't be effectively changed by users. This should be either removed or disabled.
