Can the DE10-Nano use RS422 protocol? I have checked the manufacturers website and it shows that to use RS422 protocol on the FT232R chip you need level converters and I am not sure that the level converters are allready on the DE10-Nano because I have not received one of them yet. Does the board already have the level converters installed?
Thanks in advance.

Short answer: no, not possible.
Longer: the FT232R on the DE10-Nano is used to connect CMOS level pins (HPS_RX/TX) on the FPGA to the client side of the FT232R USB/Serial converter.
The USB goes off board to connect to some host, and will look like a Serial USB port to it.
There is no way to insert any kind of RS422 buffers (basically just differential high-speed serial signalling) in that signal path.
If you wanted to do any kind of external RS422 signaling you'd have to dedicate some I/O pins on a connector, and build/attach a small board with RS422 buffers/connector.
