How to set up a VPS for the ejudge testing system?

Question

Network administration

Good day to all!
I need to install ejudge on a VPS.
But, as you know, for correct operation and protection, you must either install a patch on the kernel, or roll up an image of the system (ejudge provides an image of Fedora's).
I read about VPS and found two of the best, in my opinion: digitalocean.com and linode.com
But, after reading more, I found out that there you can only select a system image from the list (i.e., your image is no longer there). I could not find information about the possibility of installing a patch on the kernel. Therefore, the question is: Is it possible to somehow put ejudge on the VPS provided by the two companies listed above, and if not, tell me where there is such an opportunity?
