When an ACF Accordion field is rendered on an editing page, the interaction to expand/collapse the content is contained within a div: <div class="acf-label acf-accordion-title"> <i class="acf-accordion-icon dashicons dashicons-arrow-down"></i> <label for="acf-field_5e6b4d8f8e1a6-row-1-field_5e6b66eb2ac7d">Module 2, 3, or 4 Columns</label> </div> In this way, the interaction to expand/collapse the content is not accessible via keyboard, effectively making it impossible to use without a pointing device like a mouse or trackpad. It would be useful to insert a button inside the div and delegate the function of expanding/collapsing the content to it.
