I am trying to install Ansible collections for ServiceNow (ServiceNow collections) on RHEL 8.5 using ansible version 2.9.27, however the note on provided webpage states that

Installing collections with ansible-galaxy is only supported in ansible 2.9+

Since Ansible v. 2.10 is not available for RHEL I cannot make an update to version 2.10 therefore I can't use ansible-galaxy. Is there any other way to install these collections? If not do you have any suggestions regarding other ways to install ansible 2.10 so I can use Ansible Tower with these collections?
