You can do it with one more extra step:

    steps:
      - uses: actions/checkout@v3

      - name: Get Changed Files @ all
        id: all-changes
        uses: tj-actions/changed-files@v35
        with:
          files: |
            lib/**
            tests/**

...

      - name: PHP-CS-Fixer
        uses: docker://oskarstark/php-cs-fixer-ga
        if: ${{ steps.all-changes.outputs.all_changed_files }}
        with:
          args: --config=.php-cs-fixer.base.php --diff --dry-run ${{ join(steps.all-changes.outputs.all_changed_files, ' ') }}

At this point you can create a specific config without finder.

.php-cs-fixer.base.php

<?php

$fixer = (new PhpCsFixer\Config())
    ->setRules([
        'no_spaces_after_function_name' => true,
        'no_spaces_inside_parenthesis' => true,
    ])
    ->setRiskyAllowed(true)
    ->setCacheFile('.php-cs-fixer.cache')
;

return $fixer;

.php-cs-fixer.dist.php

<?php

$fixer = require __DIR__ .'/.php-cs-fixer.base.php';

$fixer->setFinder((new PhpCsFixer\Finder())
    ->in(__DIR__.'/lib')
    ->in(__DIR__.'/tests')
    ->append([__FILE__]));

return $fixer;
