Disable 302 redirect if page doesn't exist (404) in Apache?

Question

Apache HTTP Server

The essence of the problem:
When you open a link to a non-existent page of the domain.tld/test_page type, the status 404 is immediately given.
When you open a link to a non-existent page of the domain.tld/test_page/ type (slash at the end), a 302 redirect occurs first to the same address without a slash and the status is added 404.
How can you avoid the appearance of status 302 for non-existent pages opened with a slash at the end?
All existing links should continue to redirect from versions with a slash to versions without a slash.

Let's reason logically. You have a forwarding from without a slash to a slash, and it will work everywhere. She doesn't care if the page is there or not. But there is still a way out. This redirection can be done not by means of apache, but by means of php, which can check if the page exists or not, and if it does not exist, give 404, and if it exists, give 302)
Of course, I can be wrong and maybe Apache can still do this, but I have no idea how . But I have an idea how nginx can do this. Although I haven't tested it.
