Is there a way to disable the inflatable belt so it can be used with car seats? I specifically want to do a Cybex Sirona S (wifey chose that one), and Cybex themselves haven't approved for usage with this new kind of belt. Unfortunately, I'm having a very hard time finding recent manufacturer information about compatibility (sites are from 2014, maybe 2016... nothing that's clearly modern 2021 information including the latest car seat models, which is necessary for me to have confidence we can shop the new ones we want).
