Sigh
The manhwas genre already has romance in it, most possible shes gonna end up with axion. If you want something like that find another lol (I'm not trying to be rude)
All of it are romance, harem, and ecchi. And don't worry you're not rude, I met way ruder people before.
Pathfinder is a shounen with a female mc and no romance
It's a romance and josei/shoujo genre story. If you want a strong female lead with little to no romance, you'll have to look for stories in the seinen or shounen with a female protagonist genre.
Some you might like: Sengoku Strays, Yasei no last boss ga arawareta, Juuni Kokuki, Seirei no Moribito
This one might have no romance, just two strong FLs and friendship, one of supporting male character loves the first FL tho but still the story isn't focused on romance

Try Kill the Villainess. From the spoilers ive read, im pretty sure there is n romance and mc actully fulfills her goal
Ah--- I really love Moribito.
(But I also like that Mr. Tanda is essentially the wife who waits at home XD...)
Oh---hmm, technically an anime and not a manga but I really liked Le Chevalier D'eon. The plot was very interesting and so was the ending.
The main character is a nobleman who is possessed by the ghost of his dead twin sister. She takes over his body to slay demonic curses, and he gathers companions to unravel mystery of how and why she died.
The dead sister is really cool, and hot, and has badass villainess vibes. It was more story focused than romance focused.
Kill the Villainess actually has a teeny weeny bit of romance. But most of the plot is how the MC is gonna go back and the obstacles she faces.
Please no romance, let her be in peace. But I know this will be in vain because all badass female always have a man besides her *sigh* God why can't we have a badass female with no romance for ONCE
