VPS, Virtual Private Server advice

I'm running Centos 8, server, and need a private virtual server to simple web hosting for individual training so spend some hours to find a free one, for couple of day. Digital Ocean, Azure and Google they either require credit card info or telephone and address confirmation. Have been through reddit as well but no advice. Could anyone give any advice for a good free one, being able to register without any private info ? There are also so,e older post in here, but much older to be used or has become absolute, literally from 2005.
