Xavier NX PCIE Endpoint Mode with JetPack 5.1.2 patches still needed?

Does this latest release (5.1.2) address the PCIE Endpoint Mode configuration patches with having to manually change files or is it automatically taken into account like the 4.X releases?

More simply, do we have to apply the same patches as previous 5.X releases?

See this thread for reference:

Thank you!
