If you can't get the Trellix ENS 26.x product extensions and installation packages from the Software Catalog (Software Manager on ePO - On-prem 5.9.x), you can download them from the Trellix Product Downloads site, then install them on the ePO - On-prem server.

All Trellix ENS modules installed or upgraded on a system should originate from the same source package, avoiding a mix and match of installed module versions.
