The following one-liner PowerShell cmdlet will allow you to change the default location of the Audit Log file on a DHCP Server.

Execute the following cmdlet using an elevated PowerShell Prompt from the target DHCP Server to verify that DHCP Audit Logging is enabled.

#Verify if DHCP Audit Log is enabled
Get-DhcpServerAuditLog

If Enable=True then execute the following cmdlet.

#This cmdlet will change the default location of the DHCP Audit log file under folder C:\Logs\DHCP with a maximum size of 100Mbytes
Set-DhcpServerAuditLog -Path C:\Logs\DHCP -MaxMBFileSize 100

If Enable=False then execute the following cmdlet to enable the Audit Logging and alter the default file location.

#This cmdlet will enable the Audit Logging and change the default location of the DHCP Audit log file under folder C:\Logs\DHCP with a maximum size of 100Mbytes
