Since a value of true does not meet the condition if (empty($this->value)) { below, the option to accept null is not does not apply in web/core/modules/views/src/Plugin/views/filter/BooleanOperator.php.
if (empty($this->value)) {
if ($this->accept_null) {
if ($query_operator === self::EQUAL) {
$condition = (new Condition('OR'))
->condition($field, 0, $query_operator)
->isNull($field);
}
else {
$condition = (new Condition('AND'))
->condition($field, 0, $query_operator)
->isNotNull($field);
}
$this->query->addWhere($this->options['group'], $condition);
}
else {
$this->query->addWhere($this->options['group'], $field, 0, $query_operator);
}
}This is possible to get around by simply setting 'Is equal to' 'False' instead of 'Is not equal to' 'True' of course, so this is a minor issue.
Allow 'Accept null' to be used when 'Is not equal to' is selected as well.
Provide patch and tests.

Views Boolean filter now allows accept null on 'Is not equal to' value of 'True'.
