If you mean can you combine two accounts, the answer is no. eBay used to allow this, but no more.
If you mean can you have two accounts, the answer is yes. You have to use a different email address for each account, and the accounts must never interact.
Take a look at this: https://www.ebay.com/help/policies/identity-policies/multiple-accounts-policy?id=4232
