'Dereference of a possibly null reference ... Can my code be simplified?

My project is .Net-6 Blazor WebAssembly (hosted) in C#. Can my code be simplified to avoid nullable warnings? I want the person's customer-ID in a page variable from the ApplicationUser object's Identity Name (variable is '_Name'). Thanks.

List<Person> listPersons = (List<Person>)(await PService.GetPersons()).ToList();
Person oPerson = new Person();
if (listPersons != null){
    oPerson = (Person)listPersons.Where(p => p.Name!.Equals(_Name)).FirstOrDefault();
}
if (oPerson != null) {
    _UID_CUSTOMER = oPerson.UID_CUSTOMER;
}

Solution 1:[1]

You can avoid nullable warning by removing this setting from csproj file

<Nullable>enable</Nullable>

And have these settings

<PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>    
    <ImplicitUsings>enable</ImplicitUsings>
</PropertyGroup>
