Unbelievable!
You shared a screenshot here showing how little CPU the plugin uses withotu audio input. But if you have "Suspend VST 3 plug-in processing when no audio signals are received" enabled, then the plugin is literally auto-bypassed in Cubase i.e the CPU load will be exactly zero regardless of both the type and number of loaded fx-plugins.
i.e. your screenshot shows no actual information at all except - sorry to be so blunt - that you do not actually understand what it is that you were trying to do.
If you wanted to test how much CPU the plugin uses without doing any processing you would instead have to disable the processors within the plugin itself - either while sending audio through it or while having suspend disabled.
And that's the kind of support the developer is getting here - cultish stupidity, which the more regular users wouldn't want to touch with a bargepole.
Or to say it more drastically: you sort of help branding the developer as someone who's solely for the nutters and the hopelessly incompetent. And I'm not sure he'd be to happy with that kind of stigma.
And from what I read from him so far it neither didn't seem at all like the deserves this. He seemed rather reasonable, competent and down to earth to me - none of which applies to you.
