Permission to change stage by Business Process

Hi community,

I have created a business process for the Lead. There is a stage named "Converted" to show that the Lead is converted to Opportunity.

But I have to check the Account of the Lead if the Account has the status: "Green" - a look-up field, the user could allow changing the Lead Stage to Converted. If the Account doesn't have the status, then the Lead is not allowed to change the Lead stage

Is there any way for me to set it up?

Thank you!
