I've had to tinker with this in the past and it is only a set of VIs in vi.lib (and docs, examples etc) so if you really wanted this you can probably copy them from a 2020 installation to 2021 and then mass compile the folders.
I'm not saying I would necessarily recommend it! But if you needed 2021 now then it should work.

Thanks, in the end I did what you suggest James, it was only for evaluating LV2021 for the moment. But on long term I hope to have EPT available officially (or at least a communication of if it will happen)
