Yes. All functions that allocate memory memory for the result can be
controlled with flags. One of the flags controls which memory
allocator is to be used. You can configure this individually for every
option. The example bellow shows how this is done in the tls module
(look for the flag CFG_STR_SHMMEM).

static cfg_option_t options[] = {
   {"method",              .param = methods, .f = cfg_parse_enum_opt},
   {"tls_method",          .param = methods, .f = cfg_parse_enum_opt},
   {"verify_certificate",  .f = cfg_parse_bool_opt},
   {"verify_cert",         .f = cfg_parse_bool_opt},
   {"verify_depth",        .f = cfg_parse_int_opt},
   {"require_certificate", .f = cfg_parse_bool_opt},
   {"require_cert",        .f = cfg_parse_bool_opt},
   {"private_key",         .f = cfg_parse_str_opt, .flags = CFG_STR_SHMMEM},
   {"pkey_file",           .f = cfg_parse_str_opt, .flags = CFG_STR_SHMMEM},
   {"calist_file",         .f = cfg_parse_str_opt, .flags = CFG_STR_SHMMEM},
   {"certificate",         .f = cfg_parse_str_opt, .flags = CFG_STR_SHMMEM},
   {"cert_file",           .f = cfg_parse_str_opt, .flags = CFG_STR_SHMMEM},
   {"cipher_list",         .f = cfg_parse_str_opt, .flags = CFG_STR_SHMMEM},
   {"ca_list",             .f = cfg_parse_str_opt, .flags = CFG_STR_SHMMEM},
   {0}
};
