Hi sp8733638-gmail-,
I appreciate you reaching out to us here. It's great to hear that you're interested in QuickBooks Online ProAdvisor training. Training and certification is available in QuickBooks Online Accountant products. However, the option to set your preferred language isn't available at this time. However, you can review other options for accounting or financial management solutions, along with a list of Government-approved, compliant alternatives here.
If you have any other questions, feel free to reach back out. We would be happy to help!
