How to Deregister a European VAT Number

Hello. We registered for VAT numbers in the UK, Germany, France, Spain, the Netherlands, Italy, the Czech Republic, and Poland through Amazon's TBA service a few years ago. However, suddenly our Amazon Europe account was suspended, and we have not been able to sell our products through Amazon Europe for about 2 years, and now we only sell our products on Amazon North America. So, I want to cancel my European VAT number registration. My existing TBA tax accountant is asking me to pay a lot of money to cancel my VAT number. Is there any way to cancel the European VAT number without paying a lot of money? I would really appreciate your advice. Have a good time.
