Is it available to order separately? For different board thickness?

[S.Ma]

It is a board to board connector from Kyocera, typically used for LED strips. Spec here

It is on sale at most distributors such as RS Components and others.

This is only for standard thickness PCB. Otherwise, TAG Connect or MIPI-10/14 with ribbon can be used.

Not the same cost, not reusable.

Because of standard PCB thickness, it is also possible to solder a DF11-10DP Hirose connector which enables more permanent connector that supports cables with your chosen pinout, easier than ribbons or a bench of flying jumper wires...
