The preferred method of configuring the firewall settings is with a policy, particularly in a domain environment.
Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Microsoft Defender Firewall with Advanced Security >> Microsoft Defender Firewall with Advanced Security >> Microsoft Defender Firewall Properties (this link will be in the right pane) >> Public Profile tab >> Logging (select Customize), "Size limit (KB)" to "16,384" or greater.
In addition to using policies, systems may also be configured using the firewall GUI or Netsh commands. These methods may be more appropriate for standalone systems.
