muhsupoke,
Modifying the standard product EULA is easily possible (technically speaking), however, it is permitted in specific cases for authorized OEM and/or re-seller partners only. Not all re-seller partners are currently enabled to modify the Surgient VQMS product EULA.
Please directly email your question to partners@surgient.com with additional details (partner name, role, what you are trying to accomplish etc) for further discussion or clarification.
