Which keyword of the @ SuppressWarnings annotation blocks warnings of possible null pointers?

I have a line of code that may have a null pointer when accessing a variable, so idea has a warning.
I can turn off this warning by adding comments @ SuppressWarnings ("all") to the method. But I don"t want to turn off all the other warnings. So I want to know which keywords are used specifically for null pointers?
I tried @ SuppressWarnings ("null") to no avail. At the same time, I also tried all these to have no effect

    @SuppressWarnings(value = {
            "boxing",
            "cast",
            "dep-ann",
            "deprecation",
            "fallthrough",
            "finally",
            "hiding",
            "incomplete-switch",
            "nls",
            "null",
            "rawtypes",
            "restriction",
            "serial",
            "finally",
            "static-access",
            "synthetic-access",
            "unchecked",
            "unqualified-field-access",
            "unused",
    })

it's best to post the alarm code so that people can verify it when answering your questions.
back to your question, can't Intellij be suppressed directly in the pop-up menu through Alter+Enter?
