Looks like you can get away by instead passing around a pointer to the address
of the template parameter object: https://godbolt.org/z/o3Paz1.
```C++
struct A{};
templateconstexpr const A*tpo{};
constexpr A ga{};
templaterequires(a==)struct B{};
[[maybe_unused]]B<>b;
```

Slightly simplified: https://godbolt.org/z/rv97Gh.
```C++
struct A{};
templateconstexpr const A*tpo{};
templatestruct B{};
B>b;
```
```
:4:10: error: the address of 'A{}' is not a valid template argument
4 | B>b;
| ^~
Compiler returned: 1
```
