[...] there is no option in RPi IDE.
Yes, of course. For target processors other than Intel/AMD this option makes no sense, so it doesn't even appear. I hadn't realized this, sorry.
To do it on the RPi you can temporarily change the target processor to Intel, change the parsing option back to "Default", save the project, set the processor back to "Default" (or Arm or whatever it was) and save the project again.
It is easier, though, to just edit the
.lpi with any text editor and simply delete that "<Parsing>" section (or just the
<Style value="1"> value if there is anything more in there).
