Is there a nonprofit discount for Trailhead DX?

Hey @Lizzy Roberts, Hello...   I was in the same channel finding out for any non-profit discount code for DX Event, wondered by seeing the conversation on same in 2019..  Tried by hitting and get in to the link, also do joined in the community, but I can't find any discount code for the Trailhead DX. Could you help me on this, please..  Little hury & intrested to participate in this year, as need to travel out to San Fran, from India..
