Negative lookahead regexp syntax is not supported.

What you can do is use use a temporary relabel to mark metrics as "keep".
Something like this:
metric_relabel_configs:
# Drop the specific metric from all instances except primary
- source_labels: [instance_name, __name__]
regex: 'primary-00;mysql_info_schema_table_size'
replacement: 'true'
target_label: keep
- source_labels: [__name__,keep]
regex: 'mysql_info_schema_table_size;'
action: drop
- regex: keep
action: labeldrop
