Start by applying the linked @PikachuEXE patch to Nginx 1.13.10 and inspect the rejected hunks in src/http/v2/ngx_http_v2_filter_module.c, along with the listed changes in auto/modules, auto/options, and the other src files. Done means the HPACK patch applies cleanly to Nginx 1.13.10 without rejected hunks.
