How can I add double quotes to items in a Python YAML dump without ruamel.yaml?

I am generating a configuration file for a service that expects a list of double quoted string options. I want to avoid installing additional packages via pip3 -r requirements.txt as suggested in this answer and use the yaml module that came available with python 3.8.10 on ubuntu 20.04. I would like a way to solve this problem without searching for the lines and replacing them.

Python 3.8.10 (default, Sep 28 2021, 16:10:42)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import yaml
>>> yaml.__file__
'/usr/lib/python3/dist-packages/yaml/__init__.py'

python3 test.yaml

import yaml

configDict = {}
configDict["OptionList"] = [
        "\"item1/Enable\"",
        "\"item2/Disable\""
    ]

with open('./testConfig.yaml', 'w') as f:
    yaml.dump(configDict, f)

testConfig.yaml

Current output:

OptionList:
- '"item1/Enable"'
- '"item2/Disable"'

Desired output:

OptionList:
- "item1/Enable"
- "item2/Disable"

It would need to digg in documentation and source code to see if it has option to change it.

At this moment I would simply get text and use replace()

import yaml

configDict = {
    "OptionList": [
        'item1/Enable',
        'item2/Disable'
    ]
}

text = yaml.dump(configDict)
print(text)

text = text.replace("'\"", '"').replace("\"'", '"')
print(text)

with open('./testConfig.yaml', 'w') as f:
    f.write(text)

Result:

OptionList:
- '"item1/Enable"'
- '"item2/Disable"'

OptionList:
- "item1/Enable"
- "item2/Disable"

If I use default_style='"' then I get all values in " "

import yaml

configDict = {
    "OptionList": [
        'item1/Enable',
        'item2/Disable'
    ]
}

text = yaml.dump(configDict, default_style='"')
print(text)

Result:

"OptionList":
- "item1/Enable"
- "item2/Disable"
