syntax to "Rotate image" "Only portrait" in Nconvert

Which is the syntax to "Rotate image" "Only portrait" in Nconvert like in XnConvert (*) ?
(or Only landcsape/All)

Since (bug?) "Export for Nconvert..." give the same result despite of these rotate options
for example only "-rotate -90"

I'm waiting for something like -rotflag landscape|portrait|all (all or nothing)
(rflag is uses for Resize options)

(*) XnConvert Version 1.96 - windows (Oct 12 2022) - Libformat version 7.126
OR Ctrl+U in XnView MP Windows Version 1.3.1 32bits (Oct 11 2022)

In French:
Quelle est la syntaxe dans Nconvert pour faire comme dans Xnconvert rotation des images
Toute orientation/Seulement portrait/Seulement paysage

Vu que, bug ?, "Exporter pour Nconvert..." met la meme chose dans les 3 cas
ex que "-rotate -90"
j’attends qq chose comme un -rotflag landscape|portrait|all (all ou rien)

-rflag est utilisé pour Resize
-rotate_flag smooth est utilisé pour l'anti aliasing
alors -rotate_orient ?
