I don't think EU will trust Huawei at all. Recently my country Netherlands has found backdoors in Huawei equipments https://www.reuters.com/article/us-netherlands-huawei-tech/d... . and the biggest telecom in my country just banned huawei in its 5G network. I am sure this will prompt more countries to reject Huawei, especially if one of the bigger countries like Italy, France, or Spain rejects them.
