The use of third-party controllers for PS5 version games is not only in fighting games or race games (it's not the rule), but also in games that the developer chooses to not limit Dualsense. An example is the RB6 siege, when it came out in the PS5 version of the RB6, third-party controls worked for a few months, including in a response from a Ubisoft developer on reddit, he mentioned that he didn't limit it because it would impact many disabled people who couldn't use DualSense. However, in September 2021, Ubisoft made a decision to limit the RB6 Dualsense, and I remember that it was a simple update, there was no new mechanism added that justified the block. This means that it is up to the developer whether or not to limit the use of Dualsense.
