Is it still tracing, in your opinion, if u go for just the pose but use your own OC?
Changing the character doesn't magically erase the fact that you traced.
If you want a pose to use for your artwork, you can use tools where you can make your own poses, or select one from the gallery that is specifically made for artist reference instead of disrespectfully ripping off another artist. All of these below are free:
JustSketchMe
PoseMy.Art
MagicPoser
Pose Maniacs
Line of Action
Figurosity
HandArtTool (Mobile)
You can literally find all of these just by googling 'art tool pose'. There's tons more that aren't listed here, especially on android and apple play stores that's avaliable for free.
You can also use a reference image from someone who specifcially creates reference stock images for artwork and comics, like AdorkaStock on DeviantArt who's pretty famous for creating such a huge, organized gallery for artists to use for reference.
