Trap is defined by its hi-hats and its 808. If you do not mention rolls and sliding 808s, Suno gives you a generic rap beat instead.

The 808 and hat pattern are the genre, so keep influence high; slightly higher Weirdness helps the melody avoid cliché.
Tips for better trap results
Ask for 'sliding 808' explicitly — it is what makes the low end feel like trap.
Add ad-libs in the lyrics in parentheses; Suno usually performs them.
'Half-time feel' at 140 BPM reads as trap, while 70 BPM often reads as slow soul.
