FWIW you could specify a list of UUIDs to skip at source:

Expand disclosure triangle to view JS source 
(() => {
    "use strict";

    // A list of UUID strings to skip.
    const exclusions = [
        // e.g. as comma-separated strings:
        // "DD24A07A-C07B-4A67-A1E6-0DF8569C473D",
        // "4F71F3BC-4F46-48B2-805F-AEC8EA77E418"
    ];

    const main = () => {
        const
            km = Application("Keyboard Maestro"),
            macros = km.macros;

        return sortBy(
            flip(compare)
        )(
            zipWith3(
                u => t => k =>
                    exclusions.includes(u)
                        ? []
                        : [`${new Date(t).getTime()} -> ${u} -> ${k}`]
            )(
                macros.id()
            )(
                macros.modificationDate()
            )(
                macros.name()
            )
            .flat()
        )
        .join("\n");
    };
