How to disable Querying Ec2 metadata

In non-cloud environment, issuing the request to http://169.254.169.254/latest/meta-data   causes delay in execution:

Facter: Querying Ec2 metadata
Facter: Trying to connect to http://169.254.169.254/latest/meta-data/ but got: execution expired

How to disable this query (don't need it in a non-cloud environment)?

Tried setting the environment variable FACTER_virtual=generic but that does not suppress this query in non-cloud environment.
