I’ve been using some simple CSS and it seems to remove them and work fine.
input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
margin: 0;
}
<input type="number" step="0.01"/>
This tutorial from CSS Tricks explains in detail & also shows how to style them
