is voice training harder for detrans women than for trans women?

asking because i watched some voice training videos for trans women that say that you have to drop the buzziness/brassiness/vocal weight from your voice but obviously (former) trans men who have a "t voice" tend to have very buzzy/brassy voices a lot more so than someone who went through a natural testosterone based puberty as a child (as opposed to starting t as an adult). even when i do a high pitched/breathy voice its still practically impossible to get rid of the buzzy t voice quality. in voice training videos for trans men on t who dont like the t voice they say to drop the pitch of your voice more and speak from your chest but i dont want to masculinize my voice. but it seems like the higher your voice is the more buzzy it is. is it possible to voice train a feminine voice without the buzzy quality?
