I have a bad left arm. How can I make cubing sweet potatoes easier?

I’m new to cooking. I love them for breakfast but struggle to cut them. I have excellent knives but a bad arm, small hands, and am short 😬 I don’t want to affect the texture too much, how long should I bake/microwave/boil before cutting? I also like the skins submitted by /u/Ok-Cantaloupe8470
