is it possible to reset innodb_row_lock without restart MySQL 5.7
No.
The workaround:

SHOW GLOBAL VARIABLES LIKE 'Innodb_row_lock%';
Run your query/queries
SHOW GLOBAL VARIABLES LIKE 'Innodb_row_lock%';
Programmatically subtract the values.  (Well, perhaps only Innodb_row_lock_waits can really be subtracted.)

It may be possible to use information_schema.GLOBAL_STATUS, but (in some cases) you get hit by the 'Uncertainty principle'.
In my experience, these values are &quot;typical&quot;:
Innodb_row_lock_current_waits  -- rarely more than 0
Innodb_row_lock_time  --  non interesting
Innodb_row_lock_time_avg  --  Usually 10-1000ms
Innodb_row_lock_time_max  --  Usually &lt; 50K (ms)
Innodb_row_lock_waits  --  not useful, except in your case of &quot;subtracting&quot;
Where are you hoping to take this inquiry?
