yes i after some researh i find solution i have used model observer

protected static function boot()
    {
        parent::boot();

        static::created(function ($model) {
           /* Getting the log limt */
            $setting = Setting::where(['option' => 'log_queue_size'])->first();
            if ($setting) {
                $limit = $setting->value['log_queue_size'] ?? 100;
                $logQuery = Log::get();

                $keepIds = $logQuery->take($limit)->pluck('id');
                Log::whereNotIn('id', $keepIds)->delete();
            }
           
        });
    }

You don't need to get all the records from DB you just need the count of records

/**
     * The "booting" method of the model.
     *
     * @return void
     */
    protected static function boot()
    {
        parent::boot();


        static::created(function ($model) {
            /* Getting the log limt */
            $setting = Setting::where(['option' => 'log_queue_size'])->first();
            if ($setting) {
                $limit = $setting->value['log_queue_size'] ?? 100;               
                $actualCount = Log::query()->count();

                if ($actualCount > $limit) {
                    $recordsToDelete = $actualCount - $limit;
                    Log::query()->latest()->take($recordsToDelete)->delete();
                }
            }
        });
    }
