Maybe if your company is filled with the type of people who run archlinux on their IBM era thinkpads, but otherwise I would be very surprised if could find even one or two sympathetic people who are also against installing a 2fa app. Even if you can get your manager to cave, it'll be less because they want to be "troublemakers" themselves, and more because they don't to deal with the hassle of arguing with you.
