The Huawei MAR-LX1M was now spotted on the Huawei website, although the full product page is not up yet. However, its UA profile confirms that this handset will come with Android 9.0 Pie onboard — with EMUI on top, of course — and features a full HD+ display. Given this screen resolution, it is likely that the MAR-LX1M will launch as a P30 Lite variant.
