I've reverified that install new host, check for upgrades, upgrade host and enroll certificates work fine even with ansible 2.9.10 on standalone engine installation. So there is some issue inside HCI installer, which doesn't handle python interpreter correctly.
Gianluca, could you please create a bug for that?
