Aspire A515-55G STTub30.sys usb driver from STMicroelectronics conflicts with Memory Integrity

The core driver STTub30.sys installed by STtube.inf is not compatible with the Memory Integrity setting in Win11.

Is there a compatible driver available from Acer to allow users to turn this security feature on?
