Question about HP NM-100

The "NM-100" memory card from HP Inc. is not compatible with the Huawei P30, as the Huawei P30 uses Nano Memory (NM) type memory cards and not microSD.

For the Huawei P30, you need to use a specific Nano Memory (NM) card, not a microSD card. Brands such as HP, Lexar, and original Huawei NM cards are compatible with the Huawei P30.
