Repro Code

const arg = 123;
const arg2 = true;
const arg3 = null;
const msg1 = `arg = ${arg}-${arg2}-${arg3}`;
const msg2 = `arg = ${arg || 'zero'}`;

ESLint Config

{
  "rules": {
    "@typescript-eslint/restrict-template-expressions": [
      "error",
      {
        "allowNumber": true
      }
    ]
  }
}

tsconfig

{
  "compilerOptions": {
    "strictNullChecks": true
  }
}

Expected Result

Line 4, where I use null and boolean in the expression should show an error.

const msg1 = `arg = ${arg}-${arg2}-${arg3}`;

Actual Result

Line 4, where I use null and boolean show no error.

const msg1 = `arg = ${arg}-${arg2}-${arg3}`;
