If you don't use the boat with great regularity, you can simply take the dinghy home with you. Either deflate & roll it up, or if it's a nesting dink, break it in half, so that it's easier to transport.
Also, if there's a beach within reasonable proximity, then if there's an anchorage or mooring
field nearby, there will be provisions for locking up one's dink on the beach. That, or carrying it up to your vehicle from there.
And plenty of people use things like inflatable
kayaks as their #2 tender
. With them being much easier to pack away for storage
. So that you could leave your primary dink on the mothership, at anchor.
Even to the point of putting a small #2 tender
into a backpack. Much as is done with folding, skin on frame, kayaks.
