When I click an accordion button, the bottom borderline disappears for a short moment and then appears again.
I want to remove this line after opening of collapsible div. Any solution?

Add .border-top class to accordion parent
<div class="accordion accordion-flush border-top" id="accordionFlushExample">
  <div class="accordion-item">
    <h2 class="accordion-header" id="flush-headingOne">
      <button
        class="accordion-button collapsed"
        type="button"
        data-mdb-toggle="collapse"
        data-mdb-target="#flush-collapseOne"
        aria-expanded="false"
        aria-controls="flush-collapseOne"
      >
        <b>Accordion #2 Item #1</b>

How to do it with CSS? I want to set a breakpoint.

Think of a class that would point out to the accordion items that you want your border to apply to. And simply set the border. https://mdbootstrap.com/snippets/standard/m-duszak/3342304#css-tab-view

how to make them behave like one accordion? I mean collapsing of every single point after opening of any.

Use this CSS:
.accordion-button:not(.collapsed), .accordion-button:not(.collapsed):focus  {
    box-shadow: rgb(0 0 0 / 0%) 0px 0px 0px;
}

Thanks. Can you tell me how to add dividing line above the first element too ("Accordion #2 Item #1" inside my snippet)? I need it for a grid purposes.
