const auto is_weightless = ov::util::is_weightless_enabled(m_non_npuw_props).value_or(false);
What about using the helper?

if (!it->second.as<bool>()) {
is_weightless = false;
}
} else if (m_non_npuw_props.count(ov::cache_mode.name()) &&
m_non_npuw_props.at(ov::cache_mode.name()).as<CacheMode>() == CacheMode::OPTIMIZE_SPEED) {

}
write(model_stream, is_weightless);
