VPS Cloud with another Provider

I have some sites in Hetzner, configured with VPS Cloud, Ubuntu / Nodejs.
Which are rags created with Wappler and Docker
Now also with the Aruba.it provider (Aruba Business) is possible the same service with costs and similar characteristics. I would therefore like to test new VPS Cloud projects on this provider, but when in the Project Setting I have to enter the provider I only have the possibility to choose from those proposed by Wappler
Do I have the chance to overcome this obstacle?
Thank you
