Oh we had the same idea haha!In theory Air suspension can be retro fitted , which allows you to lower the vehicle height considerably. It’s a high cost item and requires modifications to the chassis to accommodate the non standard suspension
Check out VB Air suspension. I’m not sure it would get you to 1.9m though. Also check the actual heights of the vents yourself for where you need to get under them. If the vents are on a slope in the garage that could give you less height room than you think.
