Comment unsupported method of boto3 1.23.10

[Lagovas]

This method is not supported with boto 1.23.10 but only this version supports python3.6 used for tests on centos 7. boto3 we use in our acra-ee environment, that is why it wasn't visible in CE tests. We can re-install it on EE side, but this method in python code should be patched for that...
