Repro

I have been using this config with v2

"@typescript-eslint/interface-name-prefix": [
    "error", {
        "prefixWithI": "never"
    }
],

The rule was removed in favor of naming-convention. I'm trying to configure the same

"@typescript-eslint/naming-convention": [
    "error",
    {
        "selector": "interface",
        "format": ["PascalCase"],
        "prefix": ["I"]
    }

which requires I prefix now. I did not find a way to invert the condition though.

It should be as simple as:

"@typescript-eslint/naming-convention": [
    "error",
    {
        "selector": "interface",
        "format": ["PascalCase"],
        "custom": {
            "regex": "^I[A-Z]",
            "match": false,
        }
    }
]

I'll add this to the docs
