You can use the select option to only pick the properties you want. Update like so:

const posts = await Post.find({})
        .populate("users")
        .populate({
            path:'comments',
            populate:{
                path:'user',
                select: 'name -_id'
            }
        })

Note that the _id is always returned so you can explicitly deselect it with -_id. See docs for further reading.
