executing unnecessary alters operation

The MySQL DB session is executing the query below.

ALTER TABLE wp_statistics_visitor CHANGE ID ID BIGINT(20) NOT NULL AUTO_INCREMENT

MySQL 8.0 is occur warning
0 row(s) affected, 1 warning(s): 1681 Integer display width is deprecated and will be removed in a future release. Records: 0 Duplicates: 0 Warnings: 1

recommend use BIGINT, deprecated bIGINT(nnn)

Alter does not help.
And the id column is the pk column.
alter operation is making very heavy load

An update is required immediately.
