You don't need heap to use vector or string, those use the heap by default because the default allocator uses the heap. check this:

std::array<std::byte, 512> buffer;
std::pmr::monotonic_buffer_resource mbr{buffer.data(), buffer.size()};
std::pmr::polymorphic_allocator<int> pa{&mbr};
std::pmr::vector<int> args{pa};
