This is a backport of PR #2194 as merged into main (7d6a5ef).
SUMMARY

Closes #2180
Transfer acceleration is not available for AWS GovCloud region, this PR performs the following changes

GetBucketAccelerateConfiguration operation is performed only if the user has provided accelerate_enabled option
