Is this a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch?

To help the switch to look inside tunneled traffic and apply different quality of service (QoS) settings to different types of traffic is not a use case for implementing Enhanced Transmission Selection (ETS) on an ArubaOS-CX switch. ETS is a feature that provides bandwidth allocation and priority assignment for different traffic classes based on IEEE 802.1Qaz standard. ETS does not help the switch to look inside tunneled traffic, but rather relies on the priority values in the outer header of the tunneled traffic to apply QoS settings. A better way to help the switch to look inside tunneled traffic and apply different QoS settings to different types of traffic would be to use deep packet inspection (DPI) or application visibility and control (AVC) features.
