Recording limit on A9/A7RIII/A7III

[Naterpotaiter]

Hi guys, I use Sony mirrorless cameras for wedding videos and other videos as well. My A7sII, A7S, A7II, and A6300 have all had the record limit switched off by sideloading an app that lets you do that. And I shoot over 30 minutes all the time. So I know that they got rid of the app system on the newer models. So is there a way to remove the 30 minute record limit on the new Sony's? I'm torn, I'm probably going to pre order the A7III tomorrow, but I am also debating a complete switch to Panasonic just because of the record limit.
