"i don't want any app to get installed on it..."

Technically this is impossible, since there are system apps like SystemUI and framework-res that Android needs to actually function.

But if you are talking about non-essential apps only, then perhaps you can delete them with root. Go to /system on a file manager that supports root, e.g. X-plore and Root Explorer, and delete the apps that you think are safe to delete. Be careful though, as those apps are on the /system partition and not /data for a reason. Your phone might become unstable after this.

The list of safe apps varies per manufacturer, but remember, Google is your friend!

Good luck.
