I would say ITRF2020 without a specified epoch is undefined, but the reference epoch 2015.00 is sometimes also used as default epoch in software. Which is a poor choice for data that is current epoch, because ITRF2020 wasn't even published in 2015. So, a default epoch like 2025.00 would give more accurate results.
