ruby net/http openssl security level

Is it possible to set security level in ruby when calling net::http instead of modifying openssl config?

I found out that OpenSSL has a way how to set security level through

OpenSSL::SSL::SSLContext#security_level

but how can I use it in new Net::Http request?

When I just setup

ctx = OpenSSL::SSL::SSLContext.new
ctx.security_level = 1

it is ignored by http request
