Is it possible to make the opencv.dnn module available in acap-computer-vision-sdk for axis P3265-LVE Dome Camera?

Hello anigabriel
We don't plan at the moment to extend the computer vision sdk, but you can try to rebuild it with the flags you need
https://github.com/AxisCommunications/acap-computer-vision-sdk/blob/master/sdk/Dockerfile.aarch64#L11
Once you rebuild the computer vision sdk, you can use your custom sdk to build the example application:
https://github.com/AxisCommunications/acap-computer-vision-sdk-examples/blob/master/object-detector-python/Dockerfile#L8

Here is an example of how we added more libs to the native sdk:
AxisCommunications/acap-native-sdk-examples#41

Be aware that building Opencv.dnn will allow you to use only the cpu to execute the inference, making it slow.
This is because the hardware accelerator doesn't have APIs for opencv.dnn.
