Yes! (tested on Firefox, Chrome, and Safari)
Look under “Assets”. There you can choose to edit “theme.css”.
If you scroll down near the end you will see:
/* Component: TextBox + TextArea */
.
.

If you add the following CSS underneath, it should do the trick.
/* Hack to remove little arrows (spinners) */
input::-webkit-outer-spin-button,
input::-webkit-inner-spin-button {
-webkit-appearance: none;
margin: 0;
}
input[type=number] {
-moz-appearance:textfield; /* Firefox */
}

Disclaimer:
I don’t know much about CSS and I’ve only tested this on Chrome, Firefox, and Safari. This potential solution is something I dug up from Google. Apparently the little arrows are called spinners from what I could gather.
