Latest update no longer supports MacOS Mojave, but can it still be installed on Mojave?

Hello! As a non-profit, we have a subscription license for SU Pro. Today we got prompted to update to the latest version, which states that it will no longer officially support MacOS Mojave. My question is, can it still be installed on Mojave? We are choosing to not update our MacOS at this time because doing so would make thousands of dollars worth of software unusable, and it is software we need and use. Thanks for any help.
