Can you describe more about what you are trying to achieve?
Netlify will not be able to host your Wordpress installation, but you seem to be aware of that.
Do you want to move to a Netlify site which is backed by data from a wordpress installation (like it is possible with Gatsby)?
If so, I’d advise you to put a DNS record in place at something like
wordpress.mydomain.com pointing to your Wordpress hosting. This will be the place for editors to access the CMS UI and for the site generator to get its data from.
If there are dynamic parts of your wordpress installation that you’d still like to host along your static site you can use redirect/proxy rules: https://docs.netlify.com/routing/redirects/rewrites-proxies/#proxy-to-another-service
(Though I think you should be fine without those)
