如何将字典列表中所有分区的datetime对象就地转换为UTC ISO格式？

import pytz
from datetime import datetime

def convert_to_utc(dt):
    if dt.tzinfo is None:
        dt = pytz.timezone('Asia/Shanghai').localize(dt)
    return dt.astimezone(pytz.utc).replace(tzinfo=None).isoformat()

data = [
    {"name": "A", "date": datetime(2022, 1, 1, 10, 0, 0)},
    {"name": "B", "date": datetime(2022, 1, 1, 12, 0, 0)},
    {"name": "C", "date": datetime(2022, 1, 1, 14, 0, 0)}
]

for item in data:
    if isinstance(item["date"], datetime):
        item["date"] = convert_to_utc(item["date"])
