Ue4 gui application run on cpu cloud

Hi! I made an app with ue4 which only uses gui, no rendering. Please dont ask why or state its an overkill, i know this already :). I need to run this app on a cloud server, but it wont run unless the cloud has gpu, which is very expensive. Is there a hack/workaround to this?

Like for example force sw rendering on ue4, or emulate gpu on a cpu cloud? I need ideas how to make this work.
