change permalink

hello there,

I’ve permalink setting set to something like this:

blog/%postname%

as seen in here https://snipboard.io/2hnC1k.jpg

but my brand’s permalinks became:

https://www.sitename.com/blog/brands/brand-name

Is there any way that I keep my current permalinks setting but get rid of ‘blog’ in my brand permalinks? I cannot delete blog in my permalink for SEO reason.
Thankyou
