Hello there, @Muz123,
We can only hide the number but not the "VAT Registration No." words in the purchase order. I recognize the value of removing it, as this helps you meet your business needs. I'll make sure to take note of this.
For now, you can perform the workaround provided by MichelleBh above since the transaction is taxable.
I recommend clicking the link below specific to your region. It provides you with the latest news and our product enhancements.
Additionally, you can visit the site below to learn more about any VAT-related tasks in QBO, depending on your location.
Please let us know if you need anything else. Take care.
