Laravel On click Event Button [Enable button after upload file]

I have a table which contain two buttons, one is for uploading a file and the other one is for giving score. What I want to do is to give a condition for the second button which is the scoring button, whereby it can’t be clicked (disabled) if there is no file uploaded. How can I achieve this?

Here is what my table looks like:

And here is my AdminController for the table

public function showpekerjaanppk(){
        if(Auth::user()->status=='super'){
            $pekerjaan = Pekerjaan::with('penyedia','user')->paginate();
            return view('admin.showpekerjaan', compact('pekerjaan'));
        }else{
            $pekerjaan = Auth::user()->pekerjaans;
            return view('admin.showpekerjaan', compact('pekerjaan'));
        }
        //return view('admin.showpekerjaan', compact('penyedia','pekerjaan','totalAvg'));
    }

And here is my blade file for the table

<section class="content">
    <div class="container-fluid">
        <div class="row">
            <div class="col-12">
              <div class="card">
                <div class="card-header">
                  @if (Auth::user()->status=='super')
                  <h3 class="card-title"><b>{{$penyedia->nama}}</b></h3> <br>
               
                  <h3 class="card-title">Nilai Total: <b>{{$totalAvg}}</b></h3> 
                  @else
                  <h3 class="card-title"><b></b></h3> <br>
               
                    <h3 class="card-title"></b></h3>
                  @endif
                <!-- /.card-header -->
                <div class="card-body table-responsive">
                  <table id="tabelpekerjaan" class="table table-bordered">

@if(isset($pekerjaans->yourFileCulmnName))
<td>
    <a href="/nilai/{{$pekerjaans->id}}" type="button" class="btn btn-outline-primary">Penilaian</a> //disabled untill file uploaded
</td>
@endif
