Redirect a subdomain in netlify.toml dynamically

Hello,

I have a custom domain (https://ari-web.xyz) [https://ari-web.netlify.app]
And if I wanted to for example switch domains I would not want to change a bunch of static stuff that redirects to my domain specifically
So can I make it dynamic somehow?

Current netlify.toml:

[[redirects]]
    from = "/tinycore"
    to = "https://tcl.ari-web.xyz/"
    status = 301
    force = true

any way to make the tcl subdomain be automatically
added to the domain instead of statically just putting in the
full URL?

Instead of using netlify.toml, you’d have to use _redirects file and generate that file during the build time. You can use:
