libnginx-mod-http-subs-filter 1.18.0-6ubuntu4 (riscv64 binary) in ubuntu hirsute

 Subsitution Nginx module can do both regular expression and fixed string
 substitutions on response bodies. The module is quite different from Nginx's
 native Substitution module. It scans the output chains buffer and
 matches string line by line, just like Apache's mod_substitute.
