Transport Directory / Directory for support patches not found

I found that on our QAS & PROD system the profile param DIR_TRANS are exactly the same.

I can transport to both systems.

The problem I have is to upload Support Patches from the server.

In other systems I have uploaded them assuming that sapmnt\EPS\in existed in PRODN, but I cannot find the directory usr\sap\trans\EPS\in on the PRODN system

Would it be safe to add the profile DIR_EPS_ROOT in PRODN so that I can direct the SPAM trxn to pick up the unpacked support patches from the server to a specific directory? This would be a standard change the the profile and restarting SAP correct?

Please advise and Thank YOu
