biblatex：当参考文献相同时，如何只显示名字首字母？（而不是所有姓氏相同的作者）

Question

这就是我目前使用的 biblatex 代码。

然而，我想仅有的如果有作者名字的首字母，则需要这些。需要的意思是，如果没有第一作者名字的首字母，则两个或多个参考文献将是相同的。

\usepackage[
  maxcitenames=2,
  maxbibnames=99,
  giveninits=false,
  hyperref=true,
  style=authoryear,
  useprefix=true, % for inclusion of 'de' 'da' in surname,
   labeldate=year, 
   alldates=year, 
   urldate=short,
  nohashothers=true,
  natbib=true
  ]{biblatex}

\addbibresource{references.bib}

目前，我还获得了 A. Smith（1776）和 P. Smith（2019）的首字母，这在我必须使用的引用样式中是不允许的。

在我的 references.bib 中，有 3 个人叫 Li。但只有 2 个人需要名字首字母，因为 Li et al. (2017) 在没有名字首字母的情况下是相同的（或者将一个命名为 Li et al. (2017b)，将另一个命名为 (2017b)，这是我不希望的）。但 Li et al. 2015 不需要名字首字母。

@article{LiX2017,
    title = {{Impacts of renewables and socioeconomic factors on electric vehicle demands – Panel data studies across 14 countries}},
    year = {2017},
    journal = {Energy Policy},
    author = {Li, Xiaomin and Chen, Pu and Wang, Xingwu},
    month = {10},
    pages = {473--478},
    volume = {109},
    publisher = {Elsevier},
    issn = {0301-4215}
}

@article{LiS2017,
    title = {{The Market for Electric Vehicles: Indirect Network Effects and Policy Design}},
    year = {2017},
    journal = {Journal of the Association of Environmental and Resource Economists},
    author = {Li, Shanjun and Tong, Lang and Xing, Jianwei and Zhou, Yiyi},
    number = {1},
    month = {3},
    pages = {89--133},
    volume = {4},
    doi = {10.1086/689702},
    issn = {2333-5955},
    keywords = {A04, Electric Vehicles, Electric vehicles, Indirect Network Effects, Indirect network effects, Policy Design, Policy design, Q03, R05}
}

@article{LI2015,
    title = {{Policies and Business Models for the Electric Mobility Revolution}},
    year = {2015},
    journal = {The Singapore Economic Review},
    author = {LI, YANFEI and KOCHHAN, ROBERT},
    number = {0},
    pages = {1550109},
    volume = {0},
    url = {http://www.worldscientific.com/doi/abs/10.1142/S021759081550109X},
    doi = {10.1142/S021759081550109X},
    issn = {0217-5908},
    keywords = {arf, battery cost, battery electric vehicles, bev, jel classification, n70, policy, q42, r48, singapore, supportive, tco, total cost of ownership}
}

这基本上与这个 5 年前的问题相同，但我不明白为什么我似乎无法解决这个问题。biblatex：仅针对第一作者进行姓名消歧义我使用 overleaf，所以我想我拥有最新版本。

非常感谢您的帮助！
