This pretty much discriminates against anyone over 30, suppressing zoom just forces them to use reading glasses. Which may be your intent.
这几乎是歧视 30 岁以上的人，抑制变焦只会迫使他们使用老花镜。这可能是您的意图。
One of the workarounds for such users is to use RDP or VNC to view a desktop browser and "pinch" the view of that.
此类用户的解决方法之一是使用 RDP 或 VNC 查看桌面浏览器并“捏”其视图。
Question should maybe read "how to disable" or "how to suppress". You should of course discern your devices using the user agent string.
问题应该是“如何禁用”或“如何抑制”。您当然应该使用用户代理字符串识别您的设备。
