Here are the two links that I used - https://virginmostpowerfulradio.org/wp-content/uploads/2021/08/Catholic-exemption_Template.pdf https://forunitedsolutions.org/religious-exemptions (I used the template for professors but there are other ones there for different employers)
I edited and modified parts of the templates. For example the virmostpowerfulradio had ivermectin in as a prophylactic. I used Dr. Zelenko modified protocol instead. https://covid19.onedaymd.com/2021/03/quercetin-and-zinc-zelenko-treatment.html He originally had used HCQ but he is in New York so he could no longer get it. He then used Quercetin instead.
This does not look like a religious exemption request. Was yours accepted?
rule of thumb - not to use templates and write freeform letter. There are many RE that are being rejected these days if there is a suspicion that those are not sincerely held beliefs.
