Yes, you can use a While...Loop
and ensure the verification it is based on is never met.
In the example on the page linked above, a random number is generated between 1 and 10. A new number is repeatedly generated until the Result equals 4.
To alter this scenario to be infinite, change the While Loop's verification to a number higher than 10. So, while the Result's InnerText does NotContain 11, click the Generate button. Since the number will never be 11, the loop is infinitely executed.
All the best,
