You can add a negative constraint to your requires clause to explicitly exclude std::vector from the range specialization. This forces it to fall back to the primary template.

#include 
#include 
#include 
template
class Exporter
{
public:
    void print(T const& value) {
    }
};
template
requires (!std::same_as)
class Exporter
{
public:
    void print(R& value) {
        Exporter exporter;
        for (auto&& item : value) {
            exporter.print(item);
        }
    }
};
