The Cares Act is a typical big federal bill: A dense and complex thicket of legalese including many call-outs to OTHER bills and authorizing much while leaving discretion for the details to bureaucrats. A very quick scan of the table of contents for the bill led me to this, for example -- which authorizes spending $1.32 billion "for the detection of SARS–CoV–2 or the prevention, diagnosis, and treatment of COVID–19.’’. [No, not the actions you reference]. Details of how that might be spent? Someone else will decide those, apparently.

Given how this monstrosity is written, it's quite possible that what you searched for doesn't exist IN THOSE SPECIFIC WORDS anywhere in the document despite Cares funding being used for the purpose you're concerned about.
