Hello,

Add this code for arrows to the Theme Settings > Custom CSS > Mobile

.woocommerce-product-gallery .owl-nav>div {
	top:0;
	margin-top: 0;
	height: 100%;
}

This code for the button and product variations:

.single-product-page .woocommerce-product-gallery .thumbnails {
    display: none;
}
.single-product-page .product-images-inner {
    margin-top: -15px;
    margin-left: -17px;
    margin-right: -17px;
}

Best Regards
