How to add ARIA attributes to a component

I'm trying to add some aria attributes and alt attributes to the header section of the mdb-side-nav component (See below). Is there an easy way to do this or do I need to override the component with one of my own (and if so how would I go about that):

<div data-v-5b9dec4c="" class="white-skin deep-purple-skin">
    <div data-v-4a2dcd94="" data-v-5b9dec4c="">
        <div data-v-4a2dcd94="" class="side-nav wide fixed sn-bg-4">
            <div data-v-4a2dcd94="" class="ps" style="width: 100%; height: 100%;">
                <ul data-v-4a2dcd94="" class="custom-scrollbar list-unstyled">
                    <li data-v-4a2dcd94="" class="logo-sn ripple-parent">
                        <div data-v-4a2dcd94="" class="text-center">
                            <a data-v-4a2dcd94="" href="MySite.com" class="pl-0"

I want to add an aria-label to this anchor tag

                                >
                                <img data-v-4a2dcd94="" src="My.svg.png" class=""

I want to add a alt attribute to this img tag

                                >
                                    <!---->
                            </a>
                        </div>
                    </li>
                </ul>

TIA MikeB
