Can I install private Shopify app in Shopify Plus account’s store?
A private app is something scoped to a single shop, A full access staff member would need to create it so it’s not something you can automate.
Look into Custom Apps instead:

Yes, my point was if a Shopify Plus Account created a private app, can this
app be installed in one of his stores?
