Disavow non niche related backlinks?

As title mentions. I went through a change in business category entirely and my new business still some of the links I bought from when my website was selling X.

but they are all for keywords completely unrelated, since I’m now selling Y.

should I disavow and start clean or leave them? Do they even help? My DR is still zero, there isn’t much power behind them anyway.

I think you should keep your authority links, it always sends good signals. On the other hand, I think you should create more thematic links to harmonize your link profile

No need to disavow them... just build more high quality niche backlinks...

If you can buy the High DR links then you can get the DR traffic.
