Oh my bad, seems specifying the platform is already a supported feature. In spm_repositories add:

spm_repositories(
    name = "swift_pkgs",
    platforms = [
        ".macOS(.v10_15)",
    ],
    dependencies = [
        spm_pkg(
            "https://github.com/vapor/postgres-kit.git",
            from_version = "2.3.2",
            products = ["PostgresKit"],
        ),
    ],
)
