On MOA VII 2019 I noticed a KIWI Roadster with the back hoop that latches down, up, providing needed air circulation. Don't know how it was rigged to keep the back hoop up but seemed a good way to go at least with a Roadster.
Not sure if this is what you want but with my 2011 4/4 "easy up" hood I simply tie the second and third hood frames together as per the picture.
Just make sure you do a test fit to see the "Tenax" clips on either side aren't strained. I have been using this system for years with no problems.
