Secondary IP Addresses on c7gn instances

Hi all, I am aware that the maximum number of secondary IP addresses is dictated by the instance type, as per https://docs.aws.amazon.com/ec2/latest/instancetypes/co.html#co_network We need more secondary IP addresses for our implementation, however, using a larger instance type would be cost prohibitive. Is there any way to increase the number of secondary IP addresses for an instance type? Thanks.
