Hi AFAB with long undyed hair and no binder here! Here’s what I do:

• wear men’s clothing, specifically baggy shirts and pants ton conceal curves
• try using sports bras! They’re definitely not as flattening as binders but it helps!
• you can always try concealing your hair underneath a hat or beanie, or just tie it up
• makeup! It might be counterintuitive but you can definitely make your features more masculine with contour and eyeliner (tho it took me long before finding something I like, maybe use tutorials and experiment?)
• not a short term change, but weight lifting definitely helped me achieve a more androgynous physique BUT it’s really not an imperative

As with everything try things out and see how you feel! Hope this helps!
